The paper is based on the theory of inter-function between water and rock, and losing energy in rock mass, brought forward that the water flow has head loss during water flow intruding through the coal seam effective water-resisting layer and energy waste concept for splitting rock mass, and analyzed the form of the remaining water pressure. Through the simulation experiment in the preventing water capability of water-resisting rocks in the coal seam scaleboard, studied the law, character of the losing in water head waste and the relation to pressure, water-resisting of hydrogeology and engineering geology character. Brought forward the new method of calculating the water inrush coefficient.

通过理论分析和实验研究，本文得出以下结论：高承压水在沿煤层底板隔水层导升过程中存在着明显的压力水头损失；同一地层条件下，煤层底板承压水水头压力越大其导升过程中的水头压力损耗就越大；同一水头压力条件下，地层的渗透性越差其阻水能力越强，水流导升过程中的水头压力损耗也越大；在同一介质中，当初始水头压力不同时，水流在导升过程中水头压力的衰减不同，在同一隔水介质中底板含水层水头压力越大其沿隔水层导升过程中的水头损耗也就越大，水头损耗随底板隔水层水头压力增加而呈递增趋势，另外它们相应的水头衰减速率也呈递增趋势，煤层底板隔

Those rarely refer to the researches about water pressure function mechanism. In fact, the water flow intrudes upwards with a loss of the distance water and energy wastes for splitting rocks when confined groundwater intrudes upwards through coal seam water-resisting layer. The water flow under the coal seam scaleboard consumes more energy after it intrudes at a certain height.

实际上，煤层底板高承压含水层水沿隔水底板岩层向上导升过程中，存在一定的沿程水头损失和劈裂岩体裂隙的能量损耗，下伏含水层高压水在底板隔水层下部劈裂导升一定的高度后，在导升段的能量消耗很大，这时作用于有效隔水层段下部的实际水压已远远小于含水层中的观测水压，真正作用在有效隔水层上的水压为残余水压P_c，对底板有效隔水层起破坏作用的有效水压力亦应为残余水压。

In recent years, the forever-lasting Taiwan and green architecture have become a major topic in our country. In order to resolve the runoff of rainwater resource, to prevent the spoliation of ecology and to reduce the effect of heat island, to search for the suitable mix design of the pervious concrete for Taiwan is not a small issue. Pervious concrete pavement is air permeable and water permeable, the soil underneath can be kept wet and rainwater can quickly filter into ground, so the groundwater resources can renew in time. It improves the environment of road pavement and also possesses many other advantages that improve city environment at drainage, sound absorption and skid resistance, and is suitable for the rainy and humid environment in Taiwan area. However, its high air voids results in low strength, the surface layer of highway pavement was seldom used pervious concrete due to heavy traffic loading.

近年来国内以打造永续台湾与绿建筑为未来努力的方向，为解决雨水资源流失、环境生态破坏及热岛效应扩张，研发本土透水混凝土实有其重要性，透水混凝土铺面可以使空气与水自由地有效的渗入，地下土壤可保持湿润，雨水也能够快速渗入地面至地下水，地下水资源或水位能即时更新，它改善道路铺面的环境，其它的优点尚包括具有良好排水、噪音吸附与车辆抗滑能力，适合铺设於台湾多雨多湿之环境，由於透水混凝土孔隙率较高，其强度低於一般混凝土，应用於重交通量公路面层因此受到局限。
