Example Sentences:

	1.	An aquitard stores water and transmits enough water to be regionally significant but not enough to supply individual wells . 弱透水层存水且区域性地传导大量水，但不能充分供给每个井。
	2.	The calculation result effectively indicate the change rule with the time and space of water table of the aquifer , soft dank aquifer , parameter in process of wells work in the pit 计算成果较好地刻画了基坑井群的实施过程中含水层、弱透水层水头、参数的时空变化规律。
	3.	( 4 ) water flow model experiment is made and hydraulic pressure variation is observed , " the detainment and displacement " of semipervious aquifers in the process of decreasing water is also studied (四)模拟二元结构土层，进行土样渗流试验，观测水压的变化，研究弱透水层承压水在降水过程中的“滞后和位差”现象和问题。
	4.	For impervious layer , the anti - inrushing stability of the pit is analyzed from the plastic damage of soil , but for semipervious layer , the anti - inrushing stability of the pit is analyzed from the seepage damage of soil 坑底为不透水层土时，应从土体发生突涌塑性破坏的角度进行分析；坑底为弱透水层土时，应从土体发生突涌渗透破坏的角度进行分析。
	5.	Thus , the piping - induced failure of two - layer foundation was verified as that ： mass flow firstly appears in the upper weakly permeable layer , and then underground erosion and scouring gradually occur from downstream to upstream between the serviously and weakly permeable layers 从而验证了二元结构堤基的渗透破坏模式为：首先在上层弱透水层中发生流土，然后在强、弱透水层之间发生自下游向上游的逐步潜蚀冲刷。
	6.	Combining achievements in past scientific research , this thesis summarizes some problems in the process of decreasing water , the problems contains : important parameters such as percolation coefficient , interfering radius etc ; designers get parameters from their experience and make their choice of limited prospecting materials too simply , because of the limits , designer ca n ' t make quantitative analysis on groundwater ; differences on breakwater effect of setting water - tight screen is still existed , although research evolvement in this field is done ; they ca n ' t grasp the hydrogeology parameters accurately in that it influences rightness of designing in deep excavation water - decreasing 本文结合以往的研究成果，总结了降水过程中存在的一些问题，主要包括：重要设计参数，如地层渗透性、基坑降水影响半径等，设计中仅从个人经验出发取值，对有限的勘探资料进行取舍和过分地简化。这些局限使设计者不能对地下水进行科学的定量分析，盲目性较大；深基坑降低承压水引起的周边地面沉降的研究虽已取得很大的进展，但是一些主要问题仍未解决，对防渗帷幕的实际挡水效果存在不同看法；对于弱透水层的水文地质参数一直难以准确把握，影响了深基坑降水设计的正确性。
