摘要
提出按朗肯主动土压力理论并结合普氏自然平衡拱原理 ,对人工挖孔桩护壁的侧压力进行分析和计算 ,根据护壁厚度按薄壁圆筒和厚壁圆筒的力学性状进行护壁内力的计算 ,最后结合工程实际情况对护壁强度进行核算以合理确定护壁材料和尺寸 ,供设计和施工参考。
Firstly,combined Rankine's earth pressure theory with Pushl's natural equilibrium arch theory to analyze the lateral pressure of reamed pile's well-coat Secondly,based the thickness of well-coat to calculate the internal force Finally,combined the practical situation of engineering to assess the well-coat strength in order to decide its size and materials.
