针对调压井结构向体型巨大化、地质条件多样化、受力条件复杂化发展的方向,通过建立变形协调方程、对传统结构力学改进形成结构改进法,并与有限元法、传统结构力学法计算结果进行对比,研究表明结构改进法计算结果与传统结构力学、有限元法计算的调压井内力分布规律基本一致,且结构改进法更易于手工计算、方便快捷,结果误差在5%以内,可满足结构设计需要,从总体分析可知结构改进法切实可行。对于下部埋置于岩土中、上部悬臂的调压井结构进行分析研究,给出了相应的计算改进思路,可为以后此种体型的设计提供新的计算方法。
Aiming at the huge body shape, diversified geologic conditions and the complicated development of stress conditions, the surge shaft structure is improved by the traditional structural mechanics to form a structural improvement method through the establishment of the deformation coordination equation, and is combined with the finite element method, the traditional structural mechanics method The results show that the results of structural improvement method are basically consistent with those of traditional structural mechanics and finite element method and the structure improvement method is easier to calculate by hand and the result error is less than 5% Can meet the structural design needs, from the overall analysis shows that structural improvement method is feasible. For the lower buried in rock and soil, the upper cantilever surge tank structure analysis, gives the corresponding calculation ideas to improve, and can provide a new calculation method for such body design.
