摘要:
玉磨铁路长大地质复杂隧道施工中采用了地质调查法、物探法、钻探法等多种手段进行超地质预报 工作。本文详细阐述了前震旦系昆阳群围岩突水突泥段、岩溶区、岩盐段、弱胶结砂岩段、有害气体段的超前 地质预报探测路线、方案、模式及侧重点,并列举实例进行具体说明。结果表明:(1)总结提出长大地质复杂 隧道的超前预报应采用多种手段相互结合、相互印证的模式开展预报工作;(2)地质调查法是基础,综合分析 工作是重点;动态调整地质复杂程度分级;动态调整探测手段和技术要求;(3)超前地质预报工作不仅要探明 不良地质体降低施工风险,为隧道开挖确定围岩级别、设计参数、工程措施提供依据,而且也要为全隧施工组 织优化和确保工期提供有利支撑等观点。
Abstract:
In the construction of long and large tunnels with complex geological conditions of Yuxi-Mohan Railway,the advance geological prediction was carried out by applying the geological survey method,geophysical exploration method,drilling method,etc. This paper elaborates in detail the exploration route,scheme,mode and key points of advance geological prediction for the section with water and mud inrush from surrounding rock,karst area,rock salt section,weakly consolidated sand sandstone section and section with harmful gases in Presinian System Kunyang group,and gives examples for explanation in detail. The results show that:(1)The advance geological prediction for long and large tunnels with complex geological conditions should be carried in a mode that combines multiple methods mutually corroborating each other.(2)The geological survey method is the foundation,and the comprehensive analysis is the key point. The classification of geological complexity,detection methods and technical requirements should be dynamically adjusted.(3)The advance geological prediction should identify the unfavorable geologic bodies to reduce construction risks,provide basis for determining the surrounding rock classification,design parameters and engineering measures for tunnel excavation,and provide favorable support for the optimization of tunnel construction organization and ensuring the construction period.
