摘要
Abstract
In this paper,the deep foundation pit of parking lot in shenzhen metro line 3 is regarded as research background, and based on the mechanical conditions of the recoverable anchor cable anchorage segment, the distribution regularity of interfacial stress for bonding segment is discussed in detail. The result indicated that the distribution of interfacial stress is not uniform but an exponential distribution. Based on the interfacial stress distribution regularity, a new design method called effective bonding length method is put forward, which can consider the practical distribution of interfacial stress. The new design method is used to calculate the anchor cable parameters in the practical engineering. The construction result indicated that the new design method for recoverable anchor cable is reasonable and reliable.关键词
