井阻 meaning in English
well resistance
Examples
- The vertical band drain can keep the maximum drainage vacity and capacity and reduce the well resistance to greatest extent under lateral pressure in the engineering foundation
垂直排水板在工程地基中受侧力作用下,仍保持最大的排水空间和排水能力.最大程度减少井阻影响 - ( 7 ) axisymetrical analytical solutions of vacuum preloading was deduced to compute pore water pressure and degree of consolidation , the effect of vacuum loading speed , well resistance and smear were considered
( 7 )在轴对称单井模型的基础上，推导了考虑真空荷载施加过程的真空预压下地基孔压及固结度的解析解，同时可考虑井阻、涂抹等因素。 - ( 8 ) for the sake of overcoming the shortage of the former work , axisymetrical analytical solutions of vacuum combined surcharge preloading were deduced , the effect of surcharge loading speed was considered and vacuum was regard as instantaneous load , so we can take account of effect of surcharge loading time , well resistance and smear , it is more closed to practical engineering
( 8 )根据以前真空-堆载联合预压解析解的不足之处，推导了真空-堆载联合预压下地基孔压及固结度的解析解。本文的解析解将真空荷载视为瞬时施加，而将堆载荷载的施加考虑为线性施加过程，因此可以考虑堆载施加的时间影响，与实际工程情况更摘要加接近，并可同时考虑井阻、涂抹的影响。 - Based on the equal strain consolidation model of sand drain , and neglecting the well resistance and the vertical drainage consolidation , a layered model for the nonlinear consolidation of sand drain , which accounts for the geostatic pressure varying along depth and the relationship between the average viod ratio and the logarithm of average effective stress , is presented
摘要基于砂井等应变固结模型，考虑初始有效应力沿深度变化，忽略井阻和竖向排水固结的影响，应用平均孔隙比与平均有效应力的对数关系，建立砂井非线性径向排水固结的分层计算模型，并求得常荷载作用下的径向排水固结解析解。 - That is , the partially penetrating sand drain ground is viewed as the double - layered ground , and its consolidation is analyzed with 1 - d consolidation theory , through the transformation from 3 - d consolidation to 1 - d consolidation in the region of sand drain . this can overcome the disadvantage that the excess pore water is discontinuous between the region of sand drain and under - lying soft layer . to the double - layered ground , based on the consolidation mechanism under surcharge , the excess pore water pressure calculation formula is deduced under the condition of multilevel equably loading or unloading , which perfects the consolidation theory
然后，在充分考虑竖井区井阻、涂抹作用以及土体结构损伤破坏对固结影响的基础上，将未打穿竖井地基合理地转化为双层地基，按一维固结理论计算，克服了传统固结计算方法在竖井处理区与下卧层交界面处存在孔压间断的缺点；在此基础上，从超载预压法的基本原理出发，分析了双层地基超载预压固结、沉降机理，推导了多级等速加、卸载情况下双层地基的固结计算公式，进一步完善了双层地基固结理论。
