摘要

通过有限元法模拟六边形筒、五连筒、环形咬合筒3种复杂构型筒型基础在整体下沉与调平工况下的渗流场分布

分析其渗透特性

建立整体下沉和调平工况下的临界负压计算公式并进行尺寸效应验证。结果表明

3种筒型基础的调平临界压差随倾斜角度的增大迅速减小

所提出的3种复杂构型筒型基础的渗透破坏临界压差计算方法在工程尺度范围内的误差在±5%以内。

Abstract

This study employs finite element simulations to analyze the seepage field distribution during the overall sinking and leveling conditions of three complex configurations： hexagonal bucket

clustered bucket

and annular interlocking bucket. The seepage characteristics are investigated

and formulas for calculating critical differential pressures during sinking and leveling conditions are established. And size effect validations of the formulas are conducted. The results indicate that the differential pressure for leveling decreases rapidly with increasing tilt angles for all three bucket types. The proposed methods for calculating critical differential pressures due to seepage in these complex bucket foundations exhibit an error range of approximately ±5% within engineering scales.
