TL;DR: In this paper, the results of analytical solutions and finite element analysis (FEM) were compared quantitatively to analyze the behavior of a soil beam under pore water pressure, and the results showed that the average value of the vertical stresses of each element was close to that of the pore-water pressure, while the horizontal stress became closer to symmetrical distribution as the number of elements of the soil beam were increased.
Abstract: Abstract To analyze the behavior of a soil beam under pore water pressure, the results of analytical solutions and finite element analysis (FEM) were compared quantitatively. In contrast to the results of the analytical solution, the horizontal stress obtained from the FEM did not show a symmetrical distribution. On the other hand, the horizontal stress became closer to symmetrical distribution as the number of elements of the soil beam were increased. A comparison of the horizontal stresses from the analytic solution with those obtained from Gaussian points of FEM showed that the magnitude of the tensile stress from the FEM using 3 elements was 6% of the maximum value of the analytical solution and the compressive stress from the FEM using the same elements was 37% of the maximum value of the analytical solution. The magnitude of the tensile stress from the FEM using 6 elements was 61% of the maximum value of the analytical solution and the magnitude of the compressive stress from the FEM using the elements was 83% of the maximum value of the analytical solution. Vertical stresses, which were obtained from the analytical solution, showed a continuous distribution with the depth of the soil beam, whereas the vertical stresses from the FEM showed a discrete distribution corresponding to each element. The results also showed that the average value of the vertical stresses of each element was close to that of the pore water pressure. A comparison of the vertical displacements computed at the near vertical center line of the soil beam from the FEM with those of the analytical solution showed that the magnitude of the vertical displacement from FEM using 3 elements was 35% of the value of the analytical solution and the magnitude of the vertical displacement from FEM using 6 elements was 57% of the value of the analytical solution.

TL;DR: In this paper, the effects of the following variables were taken into account: the angles of slope, wall or slope height, surcharge, strength parameters (cohesion and friction angle) and unit weight for all soils involved in the problem (fill, natural soil and foundation soil), friction angle for reinforcement-soil and fill-foundation interfaces, as well as internal and external factors of safety are calculated for different distributions of tensile force in the reinforcement layers according to the different arrangements of reinforcement layers in terms of number, length, and spacing.
Abstract: This research deals with the design of geosynthetic reinforced walls and slopes subjected to series of static compressive loading tests by the present TERRAM program The objectives of this study are suggesting an optimum geometry of reinforcement placement to lessen the width of the side slope of slopes The effects of the following variables were taken into account: the angles of slope, wall or slope height, surcharge, strength parameters (cohesion and friction angle) and unit weight for all soils involved in the problem (fill, natural soil and foundation soil), friction angle for reinforcement-soil and fill-foundation interfaces, as well as internal and external factors of safety are calculated for different distributions of tensile force in the reinforcement layers according to the different arrangements of reinforcement layers in terms of number, length, and spacing

TL;DR: Pembangunan struktur Âgedung, pertama kali dikerjakan adalah pekerjaan fondasi. as discussed by the authors , akan di analisis penggantian fondasi menerus pada bangunan lama dengan fondasi Strauss pada lantai empat and lima.
Abstract: Pembangunan struktur gedung, pertama kali dikerjakan adalah pekerjaan fondasi. Dalam merencanakan suatu fondasi untuk semua bangunan harus memperhatikan daya dukung dan biaya yang ekonomis. Proyek pembangunan pengembangan gedung kuliah Universitas Widyagama Malang memilki dua Fondasi yang berbeda yakni fondasi menerus pada bangunan lama dan fondasi Strauss pada lantai empat dan lima. Pada bangunan eksisting yang lama fondasi lajur tidak dapat diganggu dan untuk bangunan lantai empat dan lima direncanakan menggunakan fondasi Strauss. Dalam studi ini akan di analisis penggantian fondasi menerus pada bangunan lama dengan fondasi Strauss pada bangunan baru. Dari hasil perhitungan didapat daya dukung fondasi dengan menggunakan 4 tiang adalah sebesar 761.98 kN, Fondasi dengan menggunakan 6 tiang adalah sebesar 863.60 kN, Fondasi dengan menggunakan 8 tiang adalah sebesar 678.97 kN dan Fondasi yang menggunakan 12 tiang adalah sebesar 1035.061kN. Untuk Biaya fondasi Strauss yang dibutuhkan dalam Proyek Pembangunan Pengembangan Gedung Kampus II Universitas Widyagama Malang adalah sebesar Rp. 3.833.300.000,-.

TL;DR: In this paper, the authors determined the engineering properties of soil in research area, so that can know the rate of subsidence due to primary consolidation because of building load, which can have an impact on land subsidence.
Abstract: Jatinangor is an area of education in Sumedang Regency. Because many educational institutions established in this area, Jatinangor had a high level of infrastructure development. Soil plays an important role in determining the security level of infrastructure built on it. Imposition on the surface due to building load can have an impact on land subsidence. This study aims to determine the engineering properties of soil in research area, so that can know the rate of subsidence due to primary consolidation because of building load. The engineering properties of soil obtained from laboratory tests, such as unit weight, moisture content, void ratio, porosity, specific gravity, coefficient of permeability, angle of internal friction, cohesion, preconsolidation pressure, coefficient of consolidation, compression index, and swelling index. Based on the calculation bearing capacity of soil for general shear failure condition with strip footings type, the value of allowable bearing capacity ranges from 0.433 kg/cm2 – 12.064 kg/cm2. Assuming the building load addition is equal to the value of allowable bearing capacity, within 1 year the land subsidence is about 0.43 cm - 11.37 cm.
