地表硬壳层受荷时下卧淤泥层内水平应力的试验研究

A Study of the Horizontal Stress in Mucky Layer under Surface Loads

通过模型试验，研究了地表硬壳层受条形构布荷载时，下卧淤泥层内的水平应力。结果表明，在硬壳层的封闭下，淤泥层内水平应力随条形均布荷载的增加成幂函数的形式增长，且淤泥层内水平应力具有较高的数值，地表荷载在淤泥层内具有较大的影响范围。

By model testing,the horizontal stress in the mucky layer under overlying arath surface crust is studied in this paper, when the overlying crust is under strip evenly distributed loads. The study shows that the horizontal stress in the mucky layer is rather high and increases according to power law with the strip evenly distributed load,and a wide sphere of influence of earth surface loads on mucky layer is manifested.
