Upper Bound Shakedown Analysis for Geotechnical Applications

为了设计许多岩土结构，工程师需要估计在循环条件下可以承受的最大荷载，而不会造成大的永久性变形(增量倒塌)。这个量被用来推断允许的设计荷载，因此对于最大限度地提高安全性和最大限度地降低成本是至关重要的。该项目的主要目的是开发一种新的方法来预测结构在循环条件下能够承受的最大荷载而不经历增量倒塌。它将适用于广泛的岩土工程问题，包括人行道、海上基础、压实土和循环荷载基础。

To design many geotechnical structures, engineers need to estimate the maximum load that can be sustained under cyclic conditions without causing large permanent deformations (incremental collapse). This quantity is used to deduce the allowable design load and is therefore crucial in maximising safety and minimising costs. The chief aim of this project is to develop a new method for predicting the maximum load that a structure can sustain under cyclic conditions without undergoing incremental collapse. It will be applicable to a wide range of geotechnical engineering problems including pavements, offshore foundations, compacted soils, and cyclically loaded foundations.
