Loading test results indicate that the bottom resistance increases by about 100 % after grouting in the pile bottom , and the bearing capacity of the rigid pile increases by about 35 % 实测结果表明，桩底后注浆处理后，持力层的端阻力提高约100 % ，刚性桩复合地基承载力提高约35 % 。
Abstract : on the basis of chaotic model , this paper discusses the reasonable identification of relativistic deformation on ground capacity in plate loading test according to the result of the test 文摘:以混沌理论模型的分析值为基础，以现场载荷试验的结果为依据，对载荷试验法确定地基承载力时相对变形值的合理取定进行了论述
In designing high - rise building , it is found that the bearing capacity of natural soil usually could not meet our requirement because of the very great vertical and horizontal loads which makes the piled raft foundation is in general use 高层建筑设计中，垂直、水平荷载都很大，天然地基承载力往往不能满足设计要求，从而使桩筏基础成为被普遍采用的基础形式。
It is often the case in foundation engineering that foundation subsoils are consisted of more than one layer . up to now , hansen ' s method and meyerof ' s method for two - layered subsoils are the only two options for estimating the bearing capacity 这类非均质介质基础的极限承载力计算目前常用的是汉森加权平均法和迈耶霍夫的双层地基承载力计算公式这两种方法。
Abstract : the design principle of composite foundation is given . calculation of bearing capacity of composite foundation , calculation of deformation and soft cushion is studied . the research problems of composite foundation technique are proposed 文摘:提出了复合地基的设计原则，对复合地基承载力计算、变形计算、柔性垫层进行了探讨，提出了复合地基技术需研究的问题。
Stone pile is of great effects to the rate of ground consolidation , but increasing the bearing capacity is restrained , although cfg pile is effective to increase ground bearing capacity , it is of little effect to ground consolidation 碎石桩可以加快地基土的固结速率，但提高地基承载力的能力是有限的； cfg桩虽然可以大大提高地基承载力，但加快地基土的固结作用不大。
The comparison of results with existing solutions to minimize the influential factors of bearing capacity as well as the reduction factors of the bearing capacity of rectangular footings near excavations were given finally 最后将计算结果与已有文献资料进行了分析比较，并以地面水平时矩形基础地基承载力系数为基准，得到临近基坑矩形浅基础地基承载力减损因数上界估算值。
Application of cpt technology in the loess area , the bearing capacity of artificial composite ground is determined . moreover , the correspondence relationship between the curve feature of cpt and the compact effect of lime - mud soil compact pile is discussed 论述了静力触探( cpt )技术在黄土地区对人工复合地基承载力的确定，以及静力触探曲线特征与灰土挤密桩挤密效果的对应关系。
