摘要
钻孔压水试验是一种在钻孔内进行的岩体原位渗透试验,主要是为了探测岩体的裂隙性和渗透性,为制定防渗措施和基础处理方案等提供重要依据,广泛应用于水利、洞室工程,多在陆域进行。主要介绍了海域实际工作中抑制潮汐干扰、基岩强风化层止水不佳的方法,并重点阐述了该方法在厦门东通道海底隧道水文地质勘察中的应用效果。
Pressure water test in borehole is a rock-situ permeability test carried out in the borehole that in order to detect fracture and permeability of rock.The test provides an important basis for developing anti-seepage measures and programming foundation treatment and so on.It is widely used in hydraulic engineering,cavity engineering where more in land area.The methods including the inhibition of tidal interference at sea and good sealing in strong weathered layer is introduced.This paper mainly elaborates application results of the method which is used to hydro-geological survey in Submarine Tunnel in east channel,Xiamen.
