摘　　要：针对传统的挤扩支盘桩静荷载试验程序复杂、试验成本高等问题,该文开展挤扩支盘桩抗压抗拔同步静载荷试验,介绍挤扩支盘桩中桩与支、盘的布设方案,给出挤扩支盘桩抗压抗拔同步试验的实施步骤,结合现场静载试验获得抗压抗拔试验的荷载与变形关系,分析挤扩支盘桩在深圳地区的承载力特性,阐明挤扩支盘桩抗压抗拔同步静载荷试验在深圳地区的适用性,对其他地区的挤扩支盘桩静载荷试验具有一定的借鉴意义。Aiming at the problems of complex procedures and high test costs for traditional static load test of squeezed branches and plates piles,this paper carries out synchronous static load tests of squeezed branches and plates,introduces the layout plan of the pile,branches and plates in the squeezed branches and plates pile,and gives the implementation steps of the synchronous test of compressed and plates piles.Combined with the on-site static load test,the load-deformation relationship of the compression and pullout test is obtained,and analyzes the bearing capacity characteristics of squeezed branches and plates pile in Shenzhen.The applicability of the synchronous static load test of squeezed branches and plates piles in Shenzhen is clarified,which has certain reference significance for the static load test of squeezed branches and plates piles in other areas.
