¨¥HûbhÔÍÌbbs.3c3t.comqL_þª9ºÝ1、本场地回填土质天然含水量偏大,回填时要减少含水量,含水量以击实实验的最优含水量为准,施工方要采取保证含水量措施。¨¥HûbhÔÍÌbbs.3c3t.comqL_þª9ºÝ

¨¥HûbhÔÍÌbbs.3c3t.comqL_þª9ºÝ3、需铺土厚度不大于35cm。¨¥HûbhÔÍÌbbs.3c3t.comqL_þª9ºÝ
¨¥HûbhÔÍÌbbs.3c3t.comqL_þª9ºÝ4、每层结合层较光滑面处需采取抛毛处理。¨¥HûbhÔÍÌbbs.3c3t.comqL_þª9ºÝ
¨¥HûbhÔÍÌbbs.3c3t.comqL_þª9ºÝ5、实验室操作人员要持证上岗,避免、减少实验误差。¨¥HûbhÔÍÌbbs.3c3t.comqL_þª9ºÝ
¨¥HûbhÔÍÌbbs.3c3t.comqL_þª9ºÝ回填土施工时,施工、监理严格按实验结论指导施工:虚铺土厚度35cm,使用相同设备静压2遍,振动碾4遍(含抛毛处理的凸碾1遍),基层洒水后碾压,开挖回填土碾压前测含水量,分区域晾晒施工,试验员执证上岗,严格按实验规程操作,保证了回填土质量。后期基础施工时,人工开挖较难。特别是边坡较好:回填密实,容易成形,经过两个雨季后,5米高的边坡没有被雨水冲刷,保持了较好的形状,回填土施工受得了建设方的好评。¨¥HûbhÔÍÌbbs.3c3t.comqL_þª9ºÝ
