摘要
本文对承压水弹性动态的一些问题进行了探讨,得出如下结论:含水层孔隙压力的变幅与岩石物理力学性质有关,主要是体积弹性模量与孔隙率;开口井的水位相对于含水层孔压的相位滞后与振幅衰减普遍存在,dp=rdh的静态描述应予摒弃;在可观测的含水层埋深范围内,埋深对井潮幅度无明显影响,Melchior的潮幅随井深增加而增加的结论应予否定;Boussinesq关于应力分布的解析结果,不适用于复杂层状结构的实际地质体。
In this paper, the author studied some problems about the mechanism of elastic behavior of confined water. The following conclusions are obtained: the variation amplitude of pore pressure in aquifer depends on rook's physical and mechanical property, mainly on bulk modulus and porosity; phase lag and attenuation of amplitude of water level of opened well relative to aquifer pore pressure are widely existed. So the static expression dp=rdh should be abandoned; in the observed buried depth interval of aquifer, buried depth has no evident influence to tide difference, then the Melchior's conclusion that tide amplitude is increased with well's depth should be negtive; Boussinesq's analysis solution on stress distribution is not applicable to the geologic body with a complex layer structure etc..
