模块总装场地沉降数值分析及容许承载力研究

Numerical Analysis of Settlement and Allowable Bearing Capacity of a Modular Assembly Site

场地沉降及承载力控制是模块总装场地的重要内容之一,对预防场地失稳,确保模块组装安全具有重要意义。依据山东某模块组装场地,根据荷载试验结果修正数值模型计算参数,并结合模块总装场地荷载分布情况进行场地沉降分析。现有荷载分布下场地沉降结果不满足模块组装使用要求,通过开展模块总装场地容许承载力计算并划分场地容许承载力分布,为场地后续使用及模块组装提供参考,同时也为国内类似场地使用荷载控制提供借鉴。

Site settlement and bearing capacity control are important contents of a modular assembly site.It is of great significance to minimize site instability and ensure the safety of modular assembly.According to a modular assembly site in Shandong Province,the parameters used in the numerical model were validated by in-situ plate load test results,and the numerical analysis of the site settlement was carried out along with the load distribution of the modular assembly site.In addition,the results of the site settlement under the existing load distribution did not meet the requirements of modular assembly.This paper presents the analysis of the allowable bearing capacity of the modular assembly site.The site allowable bearing capacity distribution of the site is also presented,which provides a reference for the follow-up use of the site and modular assembly.
