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的油罐地基的平面倾斜与非平面倾斜。结果表明同时加载地表土和深层土沉降小于分别加载,在实际工程中建议采用同时加载。
When building a tank cluster on a natural soft foundation, the control of uneven settlement is critical. In order to prevent instability of the foundation during the test water, the grading loading process must be strictly controlled. Due to the duration of the project, different loading methods are applied to the tank cluster, or at the same time or separately. Based on the analysis of the influence of tank filling and uneven subsidence due to the different modes of water loading and loading, the settlement and lateral displacement of ground surface soil and deep soil are discussed in detail. The resulting tank foundation has a flat and a non-flat slope. The results show that the simultaneous loading of surface soil and deep soil subsidence is less than that of loading separately. In practical engineering, it is suggested to use simultaneous loading.
