This note presents the application of the mobilisable strength design (MSD) method to the monitoring results of the multi-propped excavation in the south area of the British Library Euston, constructed in a highly overconsolidated stiff clay deposit. The MSD method is an energy-based approach (a nonlinear finite-element method for a single-degree-of-freedom soil-wall system) introduced to develop a simplified design methodology that satisfies both ultimate and serviceability limit states. Wall displacement predictions based on the MSD method are compared with considerable field monitoring data. The sensitivity of the method to reasonable variations in input parameters is considered. A spreadsheet and python code demonstrating the MSD analysis from this paper are provided in the online supplement alongside details of the mathematical formulation.

MSD应用于大英图书馆地下室的建设：伦敦粘土的多阶段挖掘

加拿大岩土工程杂志，印刷前。
本文介绍了可移动强度设计（MSD）方法在大英图书馆尤斯顿图书馆南区多支柱开挖监测结果中的应用，该图书馆建在高度超固结的硬质粘土矿床中。MSD 方法是一种基于能量的方法（单自由度土墙系统的非线性有限元方法），旨在开发一种满足极限状态和适用性极限状态的简化设计方法。基于 MSD 方法的墙体位移预测与大量现场监测数据进行了比较。考虑了该方法对输入参数合理变化的敏感性。在线补充中提供了演示本文 MSD 分析的电子表格和 Python 代码以及数学公式的详细信息。
