For soft substratum, dig out the top layer (5-10 cm thick), sort out the animals, identify and count them.
若是软基质，用小铲挖出表面5 - 10厘米厚的基质，找出砂泥中的动物，点算和鉴定。好评(0)。
Research for the deformation and internal forces of piled raft foundation on a thick soft substratum are concerned with not only the interaction between pile, raft and soils but the also the time.
大量桩筏基础下存在较厚的饱和软弱下卧层，其变形和内力的研究不仅涉及到筏板、桩和土三者之间的相互作用，而且还跟时间有很大的关系。
When natural soil, higher bearing capacity and soft substratum in influence depth, cannot satisfy the request of bearing capacity and deformation, CFG piles are adopted to strengthen soft substratum.
天然地基土承载力较高，但基础影响深度范围内存在软弱下卧层，不能满足设计要求的承载力和变形时，采用CFG桩法对软弱下卧层进行加固处理。
