| 摘 要： | 针对在地基加固方面,确定土工格室加固地基的承载力时,仍然套用土工格橱等平面筋材加筋层的计算公式,仅对其中的某些参数进行修正,计算出的地基承载力误差较大.鉴于上述原因,基于温克尔(E Winkler)弹性地基梁理论,推导了土工格室柔性筏基的地基承载力计算公式,确定相关计算参数,并用模型试验结果验证了公式的准确性.结果表明...

| Abstract: | When determining geocell bearing capacity of reinforced foundation in the area of foundation improvement,the calculation formula about geogrid such as reinforcement layer is still applied,and only some of the parameters were modified,and the calculation error of the ground bearing capacity is large.Ground bearing capacity calculation formula of geocell flexible raft foundation was deduced based on E.Winkler's theory of elastic foundation beam.The related calculation parameters were fixed,and the accuracy of... |
