PHC管桩在深厚软土基坑支护中的应用

Application of PHC Pipe Pile in Deep Soft Pit Supporting

PHC管桩在基础工程中的应用主要以承受竖向荷载为主,但管桩用作基坑支护则是以承受水平荷载为主,深厚软土基坑支护是基坑支护的重点和难点,通过引入工程实例,探讨了PHC管桩在深厚软土基坑中应用的可行性,并在此基础上提出了PHC管桩用作基坑桩锚支护的若干原则要求。

PHC pipe pile mainly bears vertical load in foundation engineering. While PHC pipe pile is applied in deep pit supporting, mostly bears horizontal load. In deep pit supporting domain, the one of key points and difficult points is how to treat the deep soft foundation. By the analysis of engineering examples, authors discussed the feasibility of PHC pipe pile＇ s application in pit supporting, and put forward several principles about the application of PHC pipe pile in deep soft pit supporting.
