桩锚与土钉联合支护结构的工程实例

Example Projects on Composite Pit Retaining System with Anchorage Pile and Composite Soil-nail

桩锚和土钉支护结构是我国目前最常采用的两种深基坑支护形式.根据土钉与桩锚支护结构的特点及设计计算方法,通过河南省郑州市一大型深基坑工程实例,研究了桩锚与土钉联合支护结构的受力和变形特点及其设计计算方法,对类似工程具有一定的参考价值.

Anchorage pile and soil-nail retaining structures are the two types of deep foundation pit retaining system most frequently used in China. Based on the structure features and analysis approaches on soil-nail and anchorage pile pit retaining system, the loading and deforming property, together with the designing and calculating method of composite retaining system are studied in detail,and ratified by the practice of a larger-scale deep foundation pit project. It can be used as a reference for the similar projects.
