soft stratum meaning in English
软弱层
Examples
- Effect of soft strata on peak acceleration of ground motion
软弱夹层对地表加速度峰值的影响 - Selecting rational supporting type in soft stratum drift by support theory
应用支护理论合理选择软岩巷道支护形式 - Excavation and support technology of large cross section chamber in soft stratum
松软岩层中大断面硐室掘进与支护技术应用 - Successful application to many station jobsites of the fu - ba line of beijing metro program shows that using the cavern - pile method in loose soft stratum for excavating shallow buried large section tunnels is practicable . therefore it has broad prospect for application
在北京地铁“复一八线”多个车站工程中的成功应用，充分证明采用浅埋暗挖洞桩法在松散软弱地层中进行浅埋大断面洞室的开挖是可行的，具有良好的发展前景和推广价值。 - Through analyzing bed ' s response to wave , in the condition that super - stratum is more hard and second - stratum is more soft in region of interest , super static interstitial hydraulic pressure amplitude die away rapidly between stratums , before in sight of boundary between hard and soft stratum , plane effective pressure increase to max . shear stress reach peak value when bed thickness is approximately 2 . 7 meters , then it will decrease to the minimum on the place where the flexible soil has a common boundary with the rigidity , so the boundary is the most destroy plane on engineering . on the basis of reconnaissance in situ , in normal situation of sea , the structure slides to the basin along the boundary
通过对底床在波浪下的响应分析，对于研究区底床上层较硬而第二层较软的情况，超静孔隙水压力幅值在层间交界处迅速衰减，在临近硬、软地层交界处前，水平有效应力增至最大，剪切应力在底床厚度大约2 . 7米左右达到峰值，然后减小，到硬、软层土交界位置，达到最小，因此这个界面就是最容易发生破坏的工程软弱面，现场勘查证明，即使在正常海况下，构筑物也会沿坡以此交界面为滑动面，缓慢向“盆”底滑动。
