| 摘 要： | 针对含水层释水引起地面沉降问题,研制了地面沉降试验装置,进行了释水条件下含水层系统沉降试验及禁采或回灌水条件下回弹试验,并分析了各分层沉降对水位变化的响应特征.结果表明,砂层、粘性土层的沉降与水位的变化具有较好的对应关系,粘性土层沉降明显滞后于承压水位的变化,砂层具有较好的弹性,粘性土层塑性变形明显. |

| Abstract: | Aiming at the land settlement problem caused by water releasing of aquifer system, experimental device of land settlement is developed. And the settlement test of aquifer system is carried out under the condition of water releasing. Then the rebound test is carried out under the conditions of groundwater recharge or prohibition of exploitation in layered aquifer system. Finally, the response characteristics of different layer settlement to variation of water level are analyzed. The results show that the settlements of sand layer and cohesive soil layer have a good relationship with change of water level; the settlement of cohesive soil layer lags the change of confined water level; the sand layer has good elasticity and cohesive soil layer has obvious plastic deformation. |
