杭州南湖某办公园区项目结构优化设计与分析

Structural Optimization Design and Analysis of An Office Campus Project in Nanhu,Hangzhou

本项目地下室整体开发,最大长度约为640m,属于超长超大地下室结构。为考虑温度应力对大面积地下室的影响,利用不用软件分析对比。在定量分析的基础上提出控制裂缝的相关构造及施工措施。同时,针对场地内存在岩溶(溶洞)、构造带等复杂情况,为控制造价及施工安全性,进行了多方案的基础、围护、上部连桥结构等优化及方案比选。

This project basement is developed as a whole,the length of which is about 640 m,which is considered as super-long and large basement structure.Considering the effects of the large-area basement caused by temperature stress,analyzing and comparing the structural model by different software.Based on quantitative analysis,other basement concrete crack control measures and construction instructions are serving as supplements.There is also the existence of karst caves and tectonic zones within the construction site,in order to guarantee the safety of the construction and take control of the engineering cost,comparing and optimizing different plans of foundation,retaining structure and upper connecting bridge structure.
