摘要
钻爆法是隧道及地下工程应用最为广泛的施工方法之一,与之相关的超前地质预报、钻掘和爆破施工过程的机械化、信息化和智能化、隧道围岩可爆性分级、超挖预测、爆破块度分布、爆破地震效应及预防等方面近年来取得快速发展。本文就上述关键问题的国内外最新代表性研究进行总结与分析,并就主要发展方向、问题及研究方法等提出相应建议,可为隧道工程钻爆法施工技术的理论研究、工程设计与施工控制等提供有益参考。
Drill and blast method is one of the widely used construction technology in tunnel and underground engineering.Many fast progresses have been made in recent years closely related to the drill and blast method such as advanced geological prediction,mechanization,informatization&intelligentialize during drill and blast construction,classification of blastability of tunnel surrounding rock,overbreak prediction,blast fragmentation distribution,blast-induced seismic effect and prevention.This paper summarized and analyzed the key problems of above representative researches up to date both home and abroad,and put forward the corresponding propositions to the main trends,problems and research methods,which might provide helpful reference for the theoretical research,engineering design and construction control of the tunneling techniques by using drill and blast method.
