1) groundwater jacking
地下水顶托
1.
And its Karst hydro geological conditions and engineering geological condition are complex,thus the dumping site probably exist some geological problems,such as Karst leakage,Karst collapse,groundwater jacking,differential settlement,and so on.
某综合利用堆场位于三面环水的河间地块分水岭地区,堆场区喀斯特发育且涉及多条喀斯特管道水或喀斯特裂隙含水系统,其喀斯特水文地质条件及工程地质条件复杂,因而该堆场可能存在喀斯特渗漏(污染)、喀斯特塌陷、地下水顶托、不均匀沉降等地质问题。
2) uplift coefficient of ground water
地下水顶托修正系数
1.

3) flood backwatering
洪水顶托
4) push-up flood
顶托洪水
5) backwater effect
回水顶托
