摘要

针对单筒多舱筒型基础中舱压力小于边舱工况,研究其沉放过程渗流场特性;分析舱压比和中舱相对尺寸对临界吸力的影响,建立可考虑舱压比和中舱尺寸的临界吸力计算方法;分析舱压比对减小摩阻力与端阻力的影响规律,并基于有效应力原理建立可考虑舱压比的沉放需要吸力的计算方法。

Abstract

In this paper, the seepage field characteristics of multi-cell bucket foundation are studied under the condition that the middle cell pressure is less than the side cell pressure. The influence of cell pressure ratio and middle cell size on critical suction was analyzed, and the calculation method of the critical suction taking into account cell pressure ratio and middle cell size was established. Based on the principle of effective stress, a calculation method of required suctionfor the multi-cell bucket foundation was established, and the effect of middle cell size on suction drag reduction was analyzed.
