桩锚联合支护体系是将受拉杆件的一端固定在开挖基坑的稳定地层中,另一端与围护桩相连的基坑支护体系,支挡结构所承受的荷载(土压力、水压力等)通过拉杆传递到锚固体上,再由锚固体将传来的荷载分散到稳定的地层中,以维护支挡结构的稳定,它是在岩石锚杆理论研究比较成熟的基础上发展起来的一种挡土结构,安全经济的特点使它广泛的用于边坡和深基坑支护工程。主要论述某深基坑排水隧洞进水池深基坑支护设计。
Pile-anchor joint support system is one end of the tension member is fixed in the stability of the excavation pit, the other end of the retaining pile connected to the retaining system, the load bearing support structure (earth pressure, water Pressure, etc.) through the rod to the anchor, and then by the anchor will be transmitted from the load into a stable formation, in order to maintain the stability of the support structure, which is based on the theory of rock bolt developed on the basis of more mature A retaining structure, safe and economical features make it widely used in slope and deep foundation pit support engineering. Mainly discusses the deep foundation pit drainage tunnel deep foundation pit support design.
