TL;DR: In this paper, the authors show that foundations built on weak and compressible soils have suffered catastrophic failures due to foundation instability due to the instability of the underlying soil, and propose a method to prevent such failures.

TL;DR: A review of the current state of the art for additional settlement prediction techniques for footings subjected to water table rise is given in this article, where the shape of water table correction factor diagram and its extent below the footing level have been discussed based on previous studies.
Abstract: Settlement calculation is an important part in the design of shallow foundations on cohesionless soils. The designers have to ensure that the settlement is within tolerable limit. Any future rise of water table may cause additional settlement, which can jeopardize the integrity of the structure. There is no widely accepted procedure for predicting additional settlement because of water level rise. This paper reviews the current state of the art for additional settlement prediction techniques for footings subjected to water table rise. Theoretical background, analytical studies, field tests, laboratory modeling, and recent developments in predicting the effect of submergence on settlement are briefly discussed. Terzaghi (1943) suggested that the settlement is doubled when the water level rises to the footing level. This was supported by analytical studies and field experiments. Laboratory modeling of the shallow footings indicated much larger additional settlements for saturated soils. A few rational methods for predicting settlement of submerged soils have been developed based on the laboratory test results. Numerical modelings reveal that the water table correction factor can be more than two and it depends on stress level, angle of friction, and soil relative density. The shape of water table correction factor diagram and its extent below the footing level have been discussed based on the previous studies.

TL;DR: In this paper, the authors proposed an overall/modular approach with fixed elements (mitigation of soil erosion in Shahr-e-Zohak, rehabilitation of many minor sites in Kakrak, reconstruction of the bazaar in front of the Great Western Buddha, revitalization of Shahr Gholghola, removal of fragments of the Statues still in front to the niche, little museums in front in each niche) and four alternative solutions for the valorization of niches.
Abstract: The present proposal have been developed by taking into consideration the need of an integrated and sustainable development of the whole Country as well as of the local Bamiyan community. In this view, the revitalization of Bamiyan valley must be integrated in a wider perspective, defined “downstream approach”, that has been starting from the southern branch of the Silk Road, including Jam, Band-i-Amir, Bamiyan and Shar-i-Zohak. The present proposal(s) are then a first step in cultural development of the country, where the Silk Road is the ideal and physical backbone of such model. The proposal is composed by an overall/modular approach with fixed elements (mitigation of soil erosion in Shahr-e-Zohak, rehabilitation of the many minor sites in Kakrak, reconstruction of the bazaar in front of the Great Western Buddha, revitalization of Shahr-e Gholghola, removal of fragments of the Statues still in front to the niche, little museums in front to each niche) and four alternative solutions for the valorization of niches. The latter varying from empty niches to temporary reconstruction with local marble/stone realized with anthropomorphic robots.

TL;DR: In this article, an improved geotechnical design approach is proposed combining with space measurements to predict ground subsidence induced by the lowering of the water table in the Thessaly plain Carla region, Greece due to excessive pumping.
Abstract: Space technology is a new technology that provides cost-effective measurements of past displacement data. Based on these displacement measurements, within the framework of the European Space Agency’s GMES Terrafirma Project, an improved geotechnical design approach is proposed combining geotechnical modelling and space measurements to predict ground subsidence induced by the lowering of the water table. Then the proposed methodology is applied to predict future displacement at the Thessaly plain Carla region, Greece due to excessive pumping.
