摘要
在顶管工程实践中常常需要计算顶管顶进总推力,由于顶管推力计算公式很多,而且计算结果差别相当大,本文针对各计算公式进行了对比计算并分析其原因,进而提出在工程计算中应注意的有关问题。
In the pipe-jacking engineering practice,the pipe-jacking force often needs to be calculated.However the calculated results vary greatly which are from different formula.The formula are compared,clarified and classified for the convenient use.The problems worthy of being paid attention are brought forth as well.
