Abstract
China's karst area of 3.44 million km2,accounting for more than one-third of the total land area.In the process of karst tunnel construction,it is often faced with compound risks such as water inrush,karst collapse and large deformation of soft rock with high ground stress.This paper systematically reviews the latest progress of karst tunnel engineering in China in terms of geological characteristics and risk assessment system,survey technology inno-vation system,construction technology innovation and practice,groundwater environmental impact and ecological res-toration.In the future,karst tunnel engineering will focus on key scientific issues such as deepening multi-field cou-pling mechanism,green low-carbon technology innovation,intelligent equipment research and development,and col-laborative optimization of complex systems,so as to promote the fundamental transformation of karst tunnel construc-tion from"passive prevention"to"active prevention and control".关键词
