隧道与地下工程健康研究及防治理念

Research on Health of Tunnel and Underground Engineering & Its Prevention and Treatment Ideas

目前,隧道与地下工程的病害问题日益成为工程中关注的焦点问题之一,将其提升到健康的理念上来,对于工程技术进步和隧道工程学科发展具有重要意义。根据地下工程健康所处状态与使用功能的不同,将其健康状况划分为四个等级,并遴选了支护结构状态、地下水和通风照明状况等主要的健康因子作为评价量化指标。结合目前主要的声波、电磁波和激光扫面等无损检测技术,从隧道健康的防治理念出发,开发了针对地下支护结构渗漏与裂损的康复技术,对指导工程实践具有重要的实用价值。

The disease problem of tunnel and underground engineering is becoming a focus in the civil engineering at present, it has important meaning to engineering technique advancement and tunnel engineering science development to solve the disease problem with health ideas. In this paper, the underground engineering health state is classified into four grades based on the difference of the state and the function of the project, and the dominating health factors are chosen as referenced guideline, such as supporting structure state, groundwater, ventilation and illumination status etc. With Non-destructive testing technique （ NDT Tech ）, such as ： sound wave, electromagnetic and laser scanning, and at the same time, from the prevention - treatment ideas of tunnel health as the springboard, the healing technique is developed with pertinence to leakage and crack damage of the underground engineering Supporting structure, and it has important practical value to guide the engineering practice.
