| 摘 要： | 重点考察了冲击能大小、周围压力、土性对再固结变形规律的影响，对一种砂粘混合体土料制备的扰动土样进行了试验研究。这对于了解强夯冲击荷载作用下，不同土类地基的性状及其加固效果有重要意义。此外，还研究了饱和粘性土的扰动固结问题、临界孔隙水压力问题，并对不同排水条件下土体的次固结变形问题进行了讨论。

| Abstract: | The effects of some factors, such as impact loading magnitudes, confining pressure and the types of soils on reconsolidation deformation are studied under impact loading. Particularly, the reconsolidation deformation characteristics of a kind of sand-clay mixture sample are discussed according to laboratory test results; and are compared with the saturated soft clay samples. Besides, the disturbance consolidation, the limit pore water pressure, the effect of test conditions on test results, etc. are also discussed. Based on the test results, the problems of secondary consolidation deformation under various drainage conditions are analyzed. These studies have a great significance to dynamic consolidation method for the reinforcement of saturated soft clay foundation. |
