- Example Sentences:
| 1. | An aquiclude stores water but does not transmit significant amounts .
一个不透水层只存水但不能大量导水。 | | 2. | 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。 | | 3. | 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 | | 4. | When soil antecedent condition is dry and the initial rainfall intensity is high , peak surface runoff also considerably lag behind that of rainfall , because of the formation of temporary relative impermeable top layer ; b ) surface runoff is controlled primarily by infiltration - excess runoff mechanism under unsaturated condition ; the major fraction of surface runoff are dominated by saturated infiltration - excess runoff response , only a small fraction by return flow mechanism when soil is saturated ; c ) subsurface flow is dominated by saturated runoff mechanism , and the duration of subsurface post the rainfall end is dependent upon rather the soil properties than the rainfall characteristics ; d ) subsurface flow intensity in cultivated soil layer ( 0 ~ 20cm ) is high up to 35mm / h when rainfall intensity is up to 120mm / h , indicating the existing of macropores and pipe flow in cultivated layer
2 )耕作制下紫色土的产流主要机制是： 1 )当雨前土壤含水量未达到饱和状态时，表面产流起始时间有明显滞后现象，这与紫色土的快吸水性和较多非毛管孔隙密切相关；当雨前土壤较干燥，降雨初期雨强较大时，易形成临时相对不透水表层，表面产流峰也有明显滞后现象。 2 )表面径流的产流方式主要是超渗产流，当土壤达到饱和状态后，有四川大学博士学位论文小部分回归流发生，但主要是饱和超渗产流发生，因为紫色土的相对不透水层和其它透水障碍层不明显。 3 ）壤中流主要是饱和产流，与降雨过程有明显的滞后，而且雨停后的壤中流产流历时与降雨特征无关。 | | 5. | 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 |
