双排桩在长春地区基坑工程中的应用

Application of double-row piles in foundation pit engineering in Changchun area

通过对长春地区基坑工程进行双排桩支护,采用理正软件对基坑断面的位移、内力进行计算并与实际监测数据进行了比较,得出了理正软件能较好地反映出维护结构的内力和变形;双排桩有冠梁,本次工程桩身最大变形仍发生在桩顶,对今后长春地区双排桩施工具有一定的指导意义。

Through the double-row pile support for the foundation pit project in Changchun area,the displacement and internal force of the foundation pit section are calculated by using the software,and compared with the actual monitoring data,it is concluded that the rational software can be better.It reflects the internal force and deformation of the maintenance structure;the double-row pile has crown beam,and the maximum deformation of the pile body still occurs at the pile top,which has certain guiding significance for the construction of double-row piles in Changchun area in the future.
