超大型沉箱贮仓压力的数值模拟计算OACSTPCD
Numerical Simulation Study on Ballast Pressure of Ultra-large Caisson
通过ABAQUS有限元分析软件对一般沉箱和超大型沉箱的贮仓压力进行数值模拟,并对比分析数值模拟结果与按现行规范中贮仓压力公式的计算结果.经过对不同参数组计算结果的对比分析后发现:填料的内摩擦角、弹性模量、泊松比,以及填料与仓格边壁间的摩擦系数均是影响贮仓压力的主要参数.现行规范中的贮仓压力计算公式,仅考虑填料内摩擦角和填料与仓格边壁间摩擦系数的影响,而不考虑填料的弹性模量和泊松比影响的假设值得商榷.
ABAQUS finite element analysis software is used to numerically simulate the ballast pressure of common caissons and ultra-large caissons. Then the numerical simulation result is compared with the calculated result by ballast pressure formula in current design standard. It is shown that the ballast pressure is greatly affected by internal friction angle, elastic modulus, Poisson's ratio and the friction coefficient of stuffing against bunker'side wall etc. Fo…查看全部>>
