| 摘 要： | 基于水平层分析法,考虑墙后分层填土的滑动变形协调条件,建立了关于墙后分层粘性填土的挡土墙土压力强度、土压力合力和合力作用点的理论公式,并于朗肯理论公式进行了比较分析。另外,通过算例进行验证,得出墙后填料为两种粘性土时应采取的正确填筑方法。

| Abstract: | Based on the method of level-layer analysis,with the sliding harmonious condition of layered backfills considered,the theoretical answers to the unit earth pressures,the resultant earth pressures and the points of application of the resultant earth pressures on retaining walls with layered cohesive backfills are set up.The comparisons are made with Rankine's formula.In addition;another example is used to analyze the appropriate measure of backfilling as the layered backfills are two kinds of the cohesive so... |
