沉入式大直径薄壁圆筒护岸结构稳定性分析

Stability analysis of revetment structure with buried large-diameter thin-wall cylinders

将沉入式大直径薄壁圆筒等效成一个平面的刚体,根据日本规范OCDI中CELLULAR-BULKHEAD MODEL的测试结果,结合WINKLER地基模型和美国石油协会制定的API标准中p-y曲线法模拟土体对大圆筒的作用,利用ANSYS有限元法分析沉入式大直径薄壁圆筒的变形、位移以及土抗力的发展情况。实践证明,该方法计算简单、精度高,具有实用价值。

Considering the buried large-diameter thin-wall cylinder as a rigid plane body based on the results of CELLULAR-BULKHEAD MODEL test stipulated in the Japanese code OCDI,combining with the WINKLER foundation model and the p-y curve method which introduced in the American Petroleum Institute standard API,and using ANSYS finite element analysis,we analyze the deformation,displacement and the development of soil resistance of the buried large-diameter thin-wall cylinder.The method is proved by the practice simple and precise.
