竖向排水 meaning in English
vertical drainage
Examples

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。 - The mechanics of vacuum preloading was discussed by contrast of vacuum preloading and heaped preloading . the factors affecting the result of vacuum preloading for ground consolidation were as follows : the geological conditions of site , the intensity of vacuum pumping , the condition of underground water and installation of vertical drainage line . through analysis of these factors , some conceptions and design principles were proposed for vacuum preloading
在此基础上，通过堆载预压与真空预压的对比阐述了真空预压加固地基机理，分析了影响真空预压加固地基最终加固效果的各个因素：场地地质条件、抽真空作用强度、地下水赋存情况及竖向排水体的设置等。 - A method to back analysis the distribution pattern of negative pore - water pressure along vertical drainage line was proposed . some practical vacuum preloading projects were analyzed . the results showed that distribution patterns of negative pore - water pressure along the vertical drainage line were uniform and the magnitude was about half of the vacuum degree under the membrane
提出由现场实测资料反分析竖向排水体中的负压分布的方法，通过对若干工程实例的反分析，认为真空预压下负压分布沿竖向排水体的分布基本均布，其值约在膜下真空度的50左右。
