摘 要: 介绍了一种新型的先张法预应力混凝土空心支护桩,进行了部分桩型的抗弯性能试验,验证了计算方法的可靠性。工程案例应用表明,该种桩型应用在工程支护领域,特别是河道与湖泊的水系护岸、市政排水和建筑基坑等以挡土、支护为主的围护工程上具有一定的应用前景。
Abstract:A new type of pretensioned prestressed concrete hollow supporting pile is introduced,which mainly includes the products shape and the calculation of mechanical properties. And some pile types are selected for bending test to verify the reliability of the calculation method. In addition,the case application shows that in the field of support, this kind of pile has a high promotion value and application prospect in the retaining and supporting engineering of river and lake water system revetment, municipal drainage and building foundation pit as a new type of pile.
