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.

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载荷，而不会引起大的永久变形（增量坍塌）。 该量用于推导容许设计载荷，因此对于最大化安全性和最小化成本至关重要。 本项目的主要目的是开发一种新的方法，用于预测结构在循环条件下可以承受的最大载荷，而不会发生增量倒塌。 它将适用于广泛的岩土工程问题，包括路面、海上基础、压实土壤和循环加载基础。
