软土地区特殊精密装置基础微变形控制设计与实践

Design and practice of differential settlement control for soft foundation by using a special sensitive facility

首先,简要介绍了上海光源工程基础微变形控制的设计难点;其次,提出并研究了进一步减少桩基变形的技术措施与改进桩基变形计算方法相结合的微变形控制技术;最后,将现场监测结果与和本文改进计算方法得到的结果进行了对比,二者吻合较好,且现场监测结果满足了极为严格的控制要求。

Firstly,the design difficulties of differential-settlement control for the foundation of SSRF are described.Secondly,the technology of differential-settlement control with combination of technical measures of reducing settlement for pile foundation and modified settlement calculation method for pile foundation are proposed and studied.Finally,it is demonstrated that the results obtained by the proposed method agree with the measured ones of SSRF,and the measured results meet the strict design criteria for the pile foundation of SSRF.
