在Terzaghi一维固结理论基础上,推导了单级均速施加的条形、矩形、圆形荷载下单层软土地基中的超静孔隙水压力解和平均固结度表达式。基于上述理论编制了计算机程序,绘制了大量的可供直接查用的固结度计算曲线。通过研究发现荷载作用面积对地基的固结有显著的影响。作用面积越小,地基的平均固结度就越大。施工时间也是影响固结的一个重要因素。施工期越短,在相同的时间内,地基完成的固结度越大。
Based on the Terzaghi one-dimensional consolidation theory, the expressions of the excess pore water pressure solution and the average consolidation degree of single-layer soft soil foundations under single, uniform and linear loadings are derived. Based on the above theory, a computer program was compiled and a large number of consolidation curves were drawn for direct investigation. Through the study found that the area of the load effect on the consolidation of the foundation have a significant impact. The smaller the area of action, the greater the average degree of consolidation of the foundation. Construction time is also an important factor affecting consolidation. The shorter the construction period, the greater the degree of consolidation achieved by the foundation over the same period of time.
