摘　　要：具体分析了建筑工程桩基持力层选择时需要考虑的条件,包括单桩竖向承载力和成桩可行性,介绍了单桩竖向静载试验、岩基荷载试验、锚杆抗拔试验、低应变检测等确定桩基持力层承载力的常用的试验方法,以充分发挥持力岩层的特性,使建筑工程的桩基设计更加合理。The conditions that need to be considered in the selection of pile foundation bearing layer of building engineering are analyzed in detail,including the vertical bearing capacity of single pile and the feasibility of pile formation.The common test methods for determining the bearing capacity of pile foundation are introduced,such as the vertical static load test of single pile,the rock foundation load test,the anchor rod pull out test and the low strain test,so as to give full play to the characteristics of the holding rock layer and make the design of pile foundation of building engineering more reasonable.
