考虑硬壳层作用的软土地基临塑荷载计算

Calculation of proportional limit load for soft clay foundation involving the effect of dry crust

应用土力学理论和叠加原理,深入分析了软土地基上硬壳层的作用,推导出考虑硬壳层厚度和强度影响的软土地基临塑荷载计算公式,并提出了该公式计算结果的最大值界限,从而可保证这一公式应用于实际工程的可靠性。

With the help of the theory of soil mechanics and principle of superposition, the analysis is conducted deeply in the effect of dry crust on soft clay foundation, and the proportional limit load formula of soft clay foundation involving the effect of dry crust is derived. The paper also puts forward the maximum limit of the result calculated by the formula, which will ensure the reliability of the formula applied.
