TL;DR: In this paper, a concept for the design of high water protection (HWP) walls under storm surge conditions has been developed and is applied to the geometry found in the harbour of Hamburg, Germany.
Abstract: A concept for the design of high water protection (HWP) walls under storm surge conditions has been developed and is applied to the geometry found in the harbour of Hamburg, Germany. However, the design methods used have been generalized so that they may be used for a wide range of cases with similar geometries. Many gaps in standard design formulae have been filled by developing engineering approaches or formulae as reflection by steep berms, new breaker criterion, design formulae for impact breakers, reduction of loads by overtopping and soil pressure distribution in front of the wall.

TL;DR: In this article, a method and system for controlling the earth pressure in a tunnel boring or shield machine is presented, in which the chamber pressure in the chamber of the shield machine body is detected and the detected earth pressure is compared with a reference value to produce a chamber earth pressure deviation signal.
Abstract: In a tunnel boring or shield machine, a method and system for controlling the earth pressure, in which the earth pressure in the chamber of the shield machine body is detected and the detected earth pressure is compared with a reference value to thereby produce a chamber earth pressure deviation signal. In response to the chamber earth pressure deviation signal, means for controlling the amount of conveying earth accumulated in the chamber to the exterior of the machine body and/or means for advancing the shield machine body into the working face are controlled so as to maintain the earth pressure in the chamber within a predetermined range so that the breakdown of the exposed face or earth stratum as well as the rising of the ground are prevented from occurring. In another method and system, the earth pressure at the working face is detected and the detected value is compared with a reference value to produce a signal representing the earth pressure deviation at the working face.

TL;DR: In this article, a simple theory for calculating the magnitude of vertical shear loads on non-moving walls is presented, and typical results from the theory are discussed, and a companion paper presents the results of finite element calculations, case history data, and recommendations for retaining wall design.
Abstract: Retaining walls that do not move are customarily designed based on the assumption of at-rest conditions, with no consideration of vertical shear loads applied by the backfill. However, field and laboratory measurements have shown that vertical shear loads do act on nonmoving walls. A simple theory for calculating the magnitude of vertical shear loads on nonmoving walls is presented in this paper, and typical results from the theory are discussed. A companion paper presents the results of finite-element calculations, case history data, and recommendations for retaining wall design.

TL;DR: In this paper, the observational construction method is proposed whereby the excavation sequence is modified and optimized during construction, which can be used to rationalize the design at the later stages of construction.
Abstract: In excavation works, there are limitations in the ability to model earth retaining structures and select soil parameters for design. This is because of the variable and complicated retaining wall structure conditions. The soil and structure behaviour are often monitored to confirm the safety of excavation works during construction. The data are rarely used to improve predictions and modify the design of subsequent stages of construction. The back-analysis of excavations made after construction is very useful in the evaluation of the assumptions and parameters which influence the behaviour (Lambe, 1973). However, it may be advantageous to use the measured data to rationalize the design at the later stages of construction. This is an extension of the observational method described by Peck (1969). In this Paper, the observational construction method is proposed whereby the excavation sequence is modified and optimized during construction. An example of its application is given. The method can be used to revi...
