摘　　要：输水管道工程回填土压实度应符合设计要求。由于施工方法不同 ,土料含水率、虚铺厚度和压实遍数等重要参数要根据具体情况随机控制 ,即便如此 ,压实度仍然不能完全满足要求 ,经常大于 10 0 %。提出输水管道工程验收需要一个更合理的规定 ,以检测回填土压实度 。The compact density of backfill earth in water transportation pipeline construction has to meet the requirements in design stage. In field works the water content of earth, the hypo thickness of backfill and the ramming times shall be mastered to pay the score. This is difficult to do best, and sometimes it is over rammed. In this paper a better way of construction under guidelines with reason, proper earth experiment and field test of ramming compaction was proposed.
