摘要
概括近年来在渡槽抗震研究方面的新进展,提出对渡槽结构抗震性能的初步评估应遵循的原则和渡槽抗震分析应考虑的若干关键问题,全面叙述了渡槽抗震分析中地震动参数的确定原则,大型多跨渡槽的计算范围,盆式支座的简化处理,动水压力的确定,桩土相互作用的简化处理等问题。以长江水利委员会设计院初步设计的南水北调中线穿黄渡槽为例进行抗震计算分析,指出了渡槽地基系统抗震薄弱部位和应采取的工程措施。
In this paper, recent advances in aqueduct aseismatic calculation are generalized. It is put forward that principle about elementary evaluation on aqueduct structure aseismatic capability and some key problems that should be considered in the aqueduct aseismatic analysis. It is introduced that simplification treatment methods about mesh extension, bowl rubber bearings, pile-soil-structure dynamic interaction. Finally, a practice example is given to demonstrate the validity and application of simplification calculation.
