Evaluation and Suggestion of Anti-seismic Fortification Criterion Based on Seismic Damage Characteristic of Tunnel Structure in Wenchuan Seismic Disastrous Area
摘要
Abstract
Based on the seismic damage survey data of tunnel structure in Wenchuan seismic disastrous area, the highway tunnel anti-seismic fortification criterion of JTJ 004-89 Specifications of Earthquake Resistant Design for Highway Engineering is evaluated. Results show that the existing anti-seismic standard is tend to safety. The exiting anti-seismic standard can only meet fortification requirements to soft rock tunnel, but rock tunnel is able to withstand higher seismic intensity without the risk of more serious damage. The fortification standard should be to strengthen existing prevention and control provisions of fault dislocation. Take evaluation of 10 provisions about tunnel , five of which are suitable, the rest are unsuitable; and put forward specific proposals to modify. Finally, the anti-seismic fortification suggestion about tunnel structure of fault rupture zone, tunpel structure of entrance and regular period is proposed. The research results have important significance to the current code revision and anti-seismic fortification of highway tunnels.关键词
