南通地区深基坑支护优化设计的研究

针对南通地区地质土层分布的特点，对南通市某深基坑工程支护结构从支护类型的选择、支撑的布置等方面进行了优化设计，并应用理正深基坑支护结构设计软件对基坑开挖和支护过程的各工况条件进行了数值模拟，得到了围护结构的内力及位移，再与实际的监测资料进行比较，检验了设计、计算的合理性。

Research on the Optimal Design of Deep Foundation Pits in Nantong Area

According to the distribution of geological features of Nantong city, optimal design has been ap- plied to the prop-structure for deep foundation pits in terms of choosing supporting and the arrangement of support structure. This paper is intended to use software of the deep pits supporting structure to get the simulation of process of excavation and support on all conditions, and obtain the data of the internal force and displacement of structure of the building area, compared with those in practice, which proves reasonability of the design and calculation.
