织物加筋软基的实用计算方法及试验验证

本文在评述当前各家的加筋软基承载力公式的基础上,根据实地观察资料和破坏机理分析,提出了一种新的实用计算公式。据室内离心机模型试验,现场载荷试验和有限元法分析的验证,它们之间符合程度是令人满意的。鉴于这种公式以实际资料为依据,故可在工程中应用。文中并对某些系数列出了图表,以供查用。

A New Practical Calculation Method and Test Verifications of Geotextile Reinforced Soft Foundation

The current various bearing capacity formulas of the reinforced soft foundation were reviewed. The field observations were conducted, which made known the failure mechanism. On this basis, a new practical calculating formula for bearing capacity has been developed. The results from centrifugal model test, field bearing test, and finite element calculation performed for the verification of the formula showed satisfactory agreement. This formula, derived from practical informations could hence beused in practical engineering. For convenience, the diagrams and tabulated values of coefficients in this formula are also given in the paper.
