桩排式圆环拱内撑体系基坑的设计研究与实例

The design research and engineering example of pile bent circular arch internal shoring system foundation pit

简单介绍了桩排式内撑体系进行方案优化时应遵循的原则,具体阐述了圆拱支撑设计,在此基础上,分别对南都花城5号地块,宁兴城市花园C区基坑工程,冷静街1号地块商业办公楼三个实例进行了分析,提出桩排式内撑体系整体性好,造价低,工期短。

The principle that the pile bent internal shoring system planning optimization should be followed was introduced simply, the circular arch supporting design was detail illustrated, based on which the Nandu garden 5th land, Ningxing city garden C district foundation pit engi- neering and Lengiing street 1st land commercial office building were analyzed respectively, it proposed that pile bent internal shoring system in- tensity was better, the cost was low and the time was short.
