一个不透水层只存水但不能大量导水。 | | 2. | 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。 | | 3. | 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。 | | 4. | ( 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。 | | 5. | 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。 | | 6. | Intensive faults segment the aquifer system to be a complicated mulit - layer system . then , with correlative information and considering the needs for building model , strata are thus divided into sub - layers in the model : the high permeable aquifer is oif2 - 4
继而，根据有关资料，并考虑大面积建模的需要，文章对该区的含水系统作出如下分层：强透水层分别是o _ 2f ~ ( 2 - 4 。 | | 7. | 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。 | | 8. | Beven 18 suggested that when it is applied in its original form to a river basin with thin soils over an imperme - able base , the quasi - steady state approximation holds . however , he also noted that for a variety of alternative transmissivity profiles , or when the saturated depth of the aquifer is large , the deviation in the actual shape of the water table from a steady - state shape can be both large enough and last long enough to call into question the assumption of quasi - steady dynamics
Beven 18也也指出这种“拟稳定”的地下径流机制虽然能够较好地应用于那些不透水层之上的土壤厚度比较薄的流域,但对于那些非饱和土壤层的厚度随空间的变化较大也就是地下水位的变化比较大,或者潜水面的厚度较大的流域,使用这种“拟线性”的topmodel地下径流机制就容易产生问题 | | 9. | Abstract : in this article , starting from solute s transport a nd diffusion equati on , aiming at the saturation state of liquid in homogeneous soil of impermeable stratum and on the condition that lots of saturated solute ( e . g . nutriment ) on t op of the soil maintain diffusion , a strict mathematical deduction is carried ou t , and the analytical solution of solute s concentration distribution in homogeneous s o il is given
文摘:从溶质输移扩散方程出发，针对强透水层上均质土壤的液体饱和状态，在顶层含有大量饱和溶质(如养分等)维持着渗透扩散的条件下，进行严密的数学推证，给出均质土壤中溶质浓度分布的解析解。 | | 10. | 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。 |
