摘要
详细论述了广州国际体育演艺中心基坑与基础方案的选型与设计,在此基础上讨论了预应力管桩应用于基坑支护这种特殊工程,并且桩端位于类似花岗岩残积土这种遇水软化、崩解的岩土层以及场地淤泥层深厚且范围较大的特殊地质中时,易出现桩倾斜或折断以及承台外露等问题的情况,并探讨了相关的处理措施。
The design of foundation and supporting structure for its pit in Guangzhou International Sports Arena was illustrated. Based on this project, the application of prestressed concrete tube-pile to supporting structure for foundation pit was discussed, especially the pile lied on the area like granite residual soil. In addition, the problems of pile tilt, break and cap exposure appeared in the deep and wide silt field were studied, and the solution methods were put forward.
