| 摘 要： | 在使用摩擦桩为主的工程中，泥浆护壁水冲成孔的施工工艺较为成熟，可靠，对于能否把速度快，排污少，直观性强的干法螺旋钻施工工艺与水冲法两种桩型同时在工程中应用，结合工程实例进行了探讨。在静载试验、动力应变测试，数据对比的基础上，对共同应用的条件及可能性进行了分析，并就出现的施工技术问题提出可行的处理方案。

| Abstract: | Based on the friction pile in construction, the construction sequences of slurry drilling pile method is rather successful and realiable.The dry-auger drilling pile method is quick, direct and with little drainage, we will discuss issue about how to put the two methods together in practlce through practical example of project. The condition and possibility of together use are also analyzed with static load test , train test and comparison among data, and some proposals are put forward about the construction technical problems. |
