地震作用下的电梯井结构与拱坝坝体的耦联分析

在地震作用下,拱坝的附属结构电梯井与坝体的耦联分析问题已经逐渐受到水工人员的重视与研究。本文以某高拱坝电梯井结构为研究对象,分析了电梯井结构与该拱坝坝体采取不同连接方式在相应的工况下对电梯井结构应力应变影响的规律。结果表明：电梯井结构与坝体在坝顶部位设铰接连接,同时回填到一定高程时,可有效地改善电梯井结构的应力应变状况。

Coupling Analysis of Elevator Shaft Structure and Arch Dam under Earthquake

The analysis issues of the elevator shaft witch is the subsidiary structure of the dam coupled with the body have been paid attention and research by the hydraulic staffs in the role of the earthquake. Taking the elevator shaft structure in a high arch dam as for the study object, the paper analyzed the elevator shaft structure with different connection methods with the arch dam uner the corresponding operating conditions, the regulation of stress-strain for the elevator shoft structure. The results showed that: in the top of the dam site,the dam and the elevator shaft is located hinged connection while backfill to a certain height, the connection can effectively improve the stress-strain status of the elevator shaft structure.
