拱模型理论在下穿隧道稳定性评价中的应用

Geotechnical engineering stability analysis of the tunnel of Wowo Zhuang through the site of Shenmu Thermal Power Plant

窝窝庄隧道断面尺寸宽约2.7 m,高约2.9 m,穿越长度约1.3 km,从拟建中电国华神木发电有限公司2×350 MW国产超临界空冷供热发电机组场地(以下简称神华神木热电厂)穿越。通过拱模型理论分析了窝窝庄隧道与神华神木热电厂二者稳定性的相互影响;结论表明窝窝庄隧道对神华神木热电厂场地影响轻微;此论文有利于岩土工程领域隧道穿越场地的稳定性研究。

The section size of the Wowo Zhuang tunnel is about 2.7 m wide,high about 2.9 m,and the crossing length is about 1.3 km.It passes through the 2×350 MW domestic supercritical air cooled heat generating set site(hereinafter referred to as Shenmu Thermal Power Plant).Through arch model theory,the interaction between the two stability of the tunnel and Shenmu Thermal Power Plant is evaluated comprehensively.The results of various evaluation methods are basically consistent.This paper is beneficial to the stability study of tunnel crossing site in the geotechnical engineering field.
