摘要
预应力矩形支护桩是一种用于深基坑工程的新型预制桩,与传统的管桩和灌注桩相比,具有桩身质量好、抗弯刚度大、施工方便、绿色环保等优点,现已在实际工程中得到应用。结合工程实例:预应力矩形支护桩在南开大学新校区工程中的应用,结合设计比选、施工过程中的挤土效应监测和分析、开挖验证,总结该工法的设计、施工、监测的技术要点。
The prestressed rectangular supporting pile is a new type of precast pile for deep foundation pit engineering.Compared with the traditional tubular pile and cast-in-place pile,it has a good pile quality,big bending stiffness,convenient construction,green environmental protection. It has now been applied in practical engineering. Combining with the engineering example,prestressed rectangular supporting pile has been applied in new campus project of Nankai University. According to the design selection,monitoring and analysis of soil squeezing effect in the construction process and excavation verification,summarize the technology points of the design,construction and monitoring.
