三峡工程升船机上闸首基础加固处理问题研究

STUDY ON THE UPSTREAM LOCKHEAD FOUNDATION TREATMENT OF THE SHIPLIFT OF THE THREE GORGES PROJECT

通过对三峡工程升船机上闸首基础结构面进行地质概化，选取结构与基础的最不利断面，进行不处理和处理等若干不同方案的平面弹塑性有限元计算，在比较了不同方案处理效果的基础上，推荐按效果最优的方案对其进行加固处理。

Based on the geological simplification of the upstream lockhead foundation of the shiplift of the Three Gorges Project and the choice of the most disadvantageous section of the structure and foundation, several different schemes with and without reinforcement are analyzed and compared by use of two-dimensional elasto-plastic FEM. Finally, the most advantageous reinforcement scheme is recommended.
