连锁空心方桩在深基坑工程中的试验研究

Experimental Research of Chain Prestressed Spun Concrete Square Piles on Deep Excavation Engineering

本文将新近开发出的预应力基坑支护空心方护桩用于实际的深基坑工程。成功设计、施工试验段,并对试验段开挖进行监测,获得监测数据并对相关数据进行反分析,总结空心方桩用于深基坑工程的设计、施工重点,开发出深基坑工程的一种新型支护体系。

The prestressed square pile that was developed recently is applied to excavation engineering. The experimental segment wall is designed and constructed successfully. Also,the test work is oarriedout along with the excavation. Moreover,the measurement data are obtained and the inverse analysis done based on the relevant measured data. The key points during design and construction phase of excavation are summarized. Thus,a new type of retaining structure for deep excavation is developed.
