- The hydraulic fracturing technology has been developed into a reliable and practical method to determine the in - situ stress slate of underground caverns , self - bearing capability of wall rock of high - pressure cavern and the high - pressure hydraulic permeability of rock mass , which has been widely used in the disposal of nuclear waste , the long and deeply - buried communication tunnels and the high - pressure caverns of hydraulic power plant
摘要水压致裂技术现已发展成为确定地下洞室二维原地应力状态、高压洞室围岩的自身承载能力以及岩体高压透水性的可靠实用方法，并已经在核废料处置、长大深埋交通隧道以及水电站高压力洞室工程中得到广泛应用。 - In addition , this paper carry out successfully the support design practice in the preceding excavation of 4km long exploratory tunnel . according to the thesis research results , the following conclusion can be drawn . if the grouting rock can possess sound anti - seepage capability and the liner structure can hold higher hydraulic permeability relatively , and if the adjoining rock can be made as primary load - bearing structure by construction measure , the stability of country rock and the safety of liner structure will be guaranteed
计算结果表明，如果能使锦屏工程引水隧洞灌浆圈围岩具有较好的防渗性能，将高外水压力控制在灌浆圈以外，再配合透水性相对较好的支护结构以及排水措施，使灌浆圈围岩成为主要承载结构，并使衬砌结构和灌浆圈共同承载，是可以保证围岩的稳定和支护结构安全的。 - The condition of water pressure acting on the both sides of cement - soil retaining wall is researched by computing the seepage field around the wall . it is illustrated that the coefficient of water pressure , which isn ' t constant along the height , is affected seriously by some factors , e . g . , the distribution and relative hydraulic permeability of the soil beside the wall , the hydraulic permeability of its foundation , and the buried depth of the impervious layer . as a whole , the lateral pressure acting on the wall based on seepage is always smaller than that without regard to seepage in the non - excavated zone . moreover , the pressure based on seepage is greater than that without regard to seepage in the excavated zone if the coefficient of passive pressure is smaller than 1 . 176 . this case is of great advantage to the stability of the wall
通过计算水泥土挡土墙周围的渗流场，研究了墙侧水压力的变化规律.结果表明：水压力系数沿高程并非常数，且受到墙侧土层分布及其相对透水性、墙基土的透水性和下卧不透水层埋深等因素的严重影响.总体来说，考虑渗流时墙后的侧压力总小于不考虑渗流时的相应值，且当墙前的被动土压力系数较小时，考虑渗流时该侧的侧压力则大于不考虑渗流时的相应值，因此，这种情况有利于挡土墙的稳定
