| 摘 要： | 在天然软土地基上建造储罐群时,不均匀沉降的控制是关键.为了防止地基在试水过程中失稳,必须严格控制分级加载过程.由于工期的要求,对储罐群的加载方式不同,或同时加载,或分别加载.该文根据群罐在最优间距作用下,由于充水加荷方式的不同对罐基沉降和不均匀沉降的影响进行分析,详细论述了地基地表土、深层土的沉降和侧向位移以及由此产生...

| Abstract: | When constructing storage tank group on natural soft soil foundation,the control of differential settlement is very important.In order to prevent the instability of foundation during the water-falling process,the step-loading must be strictly controlled.There are two methods including loading simultaneously and loading respectively considering the time limit.This paper analyzes the impact of two methods on settlement and differential settlement of the foundation of tank group at optimum location spacing.The... |
