摘　　要：排桩加锚杆支护结构安全可靠、经济合理,因此在深基坑中得到广泛应用,目前对锚杆预应力值大小的取值和最终预应力锁定值的取值都处在半经验半理论阶段,以此出发,建立锚杆有效预应力及对土压力平衡计算模型,并应用于工程实例,结合"理正"计算软件分析预应力值施加对支护桩及土压力的影响,为今后桩锚设计中锚杆预应力施加值及最终锁定值的确定,给出一些有效的建议。The pile-anchor supporting structure is reliable and economical,therefore it is wildely used in deep excavation.At present,the choices of the anchor prestressing force value and final prestressing force locking value are both in the semi-empirical and semi-theoretical stage,thus,to establish a calculation model of anchor effective prestressing force and balance of earth pressure,applying it to actual projects,as well as combining with the culculation software of"Li Zheng"to analyze the influence of prestress value on the supporting pile and earth pressure,will provide some effective suggestions and knowledge for the determination of the applied value and final locking value of the anchor prestressing force in the future.
