摘要
本文利用现场实测资料，采用回归分析方法，在考虑了填土高度、密度，管道和槽壁间的胸腔大小，侧压力计算点距管底的高度，填土内部的摩擦力等影响管道侧向土压力的因素后，对沟理式管道侧向土压力的计算提出了新的公式。
sing the method of regressional analysis, based on the field testing data, authers present a new formula to calculate the lateral pressure of ditch conduit which severl factors affecting the lateral earth pressure such as the height of the backfill, the consolidation,the space between the conduit and the ditch, the distance between the calculating point oflateral earth pressure and the conduit bottom and the internal friction of the backfill are considered.
