Adaptive Algorithms for Lower Bound Limit Analysis. Lower bound limit analysis is a powerful new tool for predicting the maximum load that a geotechnical structure can sustain without collapsing. The results from this method are, however, dependent on the mesh used. This project aims to develop an adaptive meshing procedure for lower bound limit analysis that will iteratively optimise the mesh, subject to an accuracy condition on the computed collapse load. The aim is to produce a cost-effective solution method for use by practising engineers.

下限分析的自适应算法。下限极限分析是一种预测岩土结构在不倒塌的情况下所能承受的最大荷载的有力工具。然而，这种方法的结果取决于所使用的网格。该项目旨在开发一个自适应网格化程序下限极限分析，将迭代优化网格，计算的崩溃负载的准确性条件。其目的是产生一个具有成本效益的解决方法，供执业工程师使用。
