摘要
对地下水位变动引起风化软岩的浸水沉降机理进行了理论分析和试验研究。提出了用加、卸载剪胀系数描述地下水位变动引起沉降的简明方程式。通过试验 ,验证了在砂岩中混入适量粘性土可以有效地减轻浸水沉降的方法。
Theoretical analysis and experimental study on the immersed settlement mechanism of weathered soft rock induced by the variation of groundwater level are conducted herein and a brief equation for calculating the settlement by using the dilatation coefficient during loading and unloading is proposed. Through tests it is verified that the immersed settlement may be reduced effectively by mixing proper amount of cohesive soil into the sand rock.
