按沉降控制设计不均匀软土上的复合桩基I

为了经济有效的解决在深厚软土地基上地基变形过大,导致建筑物大量沉降,造成房屋开裂的工程问题,按照线弹性本构模型,提出了的一种关于复合桩基沉降的改进计算方法;结合具体工程实例,依据控制等沉降效应的原则,给出了一种桩基-复合桩基的地基处理方案,比较成功地解决了带有浜填土区段的软土上砖混住宅楼设计的难题.多年实测表明,计算结果比较符合实际.

Design of composition pile foundation controlled by settlement on uneven soft earth

On the deep and thick soft earth foundation,some structures have large quantity settlements and were cracked,for the foundations have oversize deformation.This paper,with some specific project in the background,according to the principles of controlling the same settlement effects,presents a version to deal with pile foundation and composition pile foundation.The version dealt with the problem successfully in designing the brick-concrete structures on soft earth ground with part of shore soil.According to the linear elastic constitutive mode,this paper also presents an improved calculation method about the settlement of composite foundation.Based on the over year actual measurement,the calculating result complies with the practice to a ctrtain exfont.and can facititate enginears and technicians with helpful reference.Some correlation engineers and technicians can reference the paper.
