填芯PHC管桩在软土基坑支护中的应用研究

Application of Centre Filler PHC Pipe Pile in Soft Soil 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,填芯PHC管桩能提高其抗弯承载力,通过引入工程实例,探讨了填芯PHC管桩在软土基坑中应用的可行性,对填芯PHC管桩在基坑支护的应用具有一定的指导意义。

PHC pipe pile mainly bears vertical load in foundation engineering. While PHC pipe pile is applied in pit supporting , mostly bears horizontal load. Centre filler PHC pipe pile to increase its flexural capacity. By the analysis of engineering examples , authors discussed the feasibility of PHC pipe pile＇s application in pit supporting , fill in the core of PHC pipe pile foundation pit supporting application has certain directive significance.
