| 摘 要： | 花岗岩风化壳从未风化岩到残积土,影响渗透性大小的空隙由裂隙过渡为孔隙,自强风化层到残积土,渗透性由大变小; 对于风化残积物承压型地下水而言,它没有传统意义的隔水层,一般强风化层水头高度最大,沿竖向渗流,随渗透性减小,水头损失增加。应用达西定律,估算水头损失。

| Abstract: | When granite weathering crust is weathered from unweathered rock to residual soil,the pore space which affects the permeability changes from fissure to pore.As the layer is from intense weathered rock to residual soil,the permeability is from strong to weak.As for residual soil confined water,there isnt an aquifuge in it.The confined water head in intense weathered rock is very high.The water flows vertically.The loss of confined water head is increasing as the permeability is decreasing.We can estimate the loss of the confined water head according to Darcys Law. |
