摘要
对于深度20m以上的软基,管桩是软基处理的可选择方案.本文介绍了PTC预应力管桩的特点、加固软基的特性、施工工艺流程和特点,并分析了施工中应注意的控制因素.
For dealing with weak subgrade of over 20m depth, tubular pile construction is an optional scheme. In this paper, the characteristics of the prestressed concrete tubular piles, the specialty of reinforced ‘weak subgrade＇ and both the technological procedure and characteristics of construction will be intreduced. The governing factors that should be paid attention in construction will also be analyzed.
