内钢板复合井壁水平承载力分析

摘要

利用相似理论对内钢板复合井壁水平承载力的影响因素进行了分析，通过对典型参数的模拟分析得到了水平承载力的主要影响因素。根据回归分析大量的模拟结果，得到了内钢板高强混凝土（ C60～C100）复合井壁水平承载力的计算公式，该公式既考虑了内钢板和混凝土的厚度几何因素，同时也考虑了混凝土强度的力学因素。经理论计算对比分析和模型试验检验，所得计算公式具有一定的适用性和可靠性。%The influence factors of horizontal loading capacity is analyzed based on similarity theory, through the simulation and analysis of typical-parameters, the main influence factors of horizontal loading capacity is obtained. Through the regression analysis of numerical simulation results, a calculation formula is proposed to estimate the horizontal loading capacity of inner steel plate and high-strength steel fiber reinforced concrete shaft lining. In the calculation formula the diversified factors related to the horizontal loading capacity are considered. According to the theoretical calculation analysis and model test, the formula has favorable applicability and reliability.
