摘要
基于ADINA软件对多舱复合筒型基础在砂土中沉贯及调平过程的渗流规律进行模拟,以渗透破坏的最不利位置为控制点,考虑了基础分舱尺寸效应,先后推导了沉贯、调平过程中复合筒型基础临界吸力的公式,总结了沉贯与调平过程中所需临界吸力随沉贯深度、分舱尺寸以及倾斜角度的变化规律。为复合筒型基础的施工提出合理化建议。
The software ADINA is used to simulate the seepage law while penetrating and leveling multi-cell composite bucket foundation in sandy soil.The most adverse seepage location serves as a control point to analyze the foundation sub-cell effect,produce the critical suction formula respectively for the penetration and leveling processes of composite bucket foundation,summarize the change rule of critical suction with the penetration depth,sub-cell size and inclined angle,and advance reasonable construction proposal.
