摘要/Abstract

摘要： 为了保证顺于路电力隧道盾构始发和到达的安全，采用弹性薄板均匀荷载模型、理想整体滑移失稳模型及土体扰动平衡理论对顺于路电力隧道端头加固范围进行了理论计算，始发端设计纵向加固长度小于理论值。为了验算设计加固范围下的安全性进行了始发模拟，考虑打开洞门、盾构到达加固体端部以及盾尾离开加固区3个工况，各项安全指标均在允许范围内，始发安全，设计范围合适。

Abstract: Theoretical calculation is made on the reinforcement scope of the end soil of Shunyulu power tunnel by means of elastic plate uniform load model, idealized sliding instability model and soil disturbance balancing theory. The calculation results show that the longitudinal reinforcement length of the launching section specified in the design is smaller than the theoretical value. Therefore, simulation is made on shield launching so as to verify the safety under the condition of the designed reinforcement scope. The simulation results show that the safety index is within the permission scope, the launching is safe and the design is proper.

Key words: power tunnel, smalldiameter shield machine, end soil reinforcement, theoretical model, launching simulation
