摘要
为研究鸡鸣山岩溶隧道智能防排水技术,首先根据岩溶监测情况,构建富水隧道排水量与地质环境稳定计算模型,利用神经网络方法建立富水隧道在排水过程中地质环境稳定的预测方法。然后基于地面塌陷、地裂缝演化机制、围岩损伤机制和灰色系统理论,建立富水隧道智能防排水模型,提出岩溶隧道施工过程智能防排水标准。最后结合前述隧道排水量预测方法,从隧道堵水、隧道截水、隧道防水、隧道排水四方面出发,以不影响施工质量、保障施工安全、保护生态环境为前提,构建富水隧道新型防排水系统,为实际施工提供指导性建议。
In order to study the intelligent waterproof and drainage technology of Jiming Mountain karst tunnel,the calculation model of the drainage volume and the stability of geological environment of the water-rich tunnel was firstly built according to the karst monitoring situation,and the prediction method of the stability of geological environment in the drainage process of the water-rich tunnel was established by using the neural network method.Then,based on ground collapse,ground fracture evolution mechanism,surrounding rock damage mechanism and gray system theory,an intelligent water-rich tunnel waterproof and drainage model is established,and an intelligent standard of waterproof and drainage is put forward for karst tunnel construction process.Finally,combined with the aforementioned method of tunnel displacement prediction,a new water-rich tunnel drainage system is constructed from four aspects,namely,water plugging,water cutting,waterproof and drainage,on the premise of not affecting construction quality,ensuring construction safety and protecting ecological environment,so as to provide guidance and suggestions for actual construction.
