盛世新天地2#楼工程基底下卵石持力层中夹有3~5m厚的性质不良的粉质黏土,经承载力及变形验算可知,不符合相关规范的要求,需要处理。对地基采用级配砂卵石换填和筏板下桩基两种方案处理后的沉降及造价进行了比对,并给出了结果。 Sandy Xintiandi 2 # Building project under the pebble bearing layer sandstone with 3 ~ 5m thick poor nature of the silty clay, the bearing capacity and deformation check shows that does not meet the requirements of the relevant norms, need to be addressed. The subsidence and cost of the foundation treated by graded sand-gravel replacement and under-raft replacement are compared and the results are given.
