结合桩列式钻孔灌注桩加角撑的典型支护结构工程实例,进行了桩身应力和变形的现场实测,采用考虑空间效应和反演方法的整体式支护结构体系的有限元分析理论,提出一整套动态施工模拟方法。通过理论研究与实测结果分析,指出了支护结构设计中的问题 Combined with the typical engineering examples of pile-supported bored piles and gussets, the on-site measurement of pile stress and deformation was carried out. The finite element analysis theory of integral support structure system considering space effect and inversion method , Put forward a set of dynamic construction simulation method. Through the theoretical analysis and the analysis of measured results, the problems in the design of support structure are pointed out
