Improvement application of construction technique of twin multiple-arch tunnel

Along with our country highway's development,double arch tunnel construction technology for tunnel construction improve continously at high speed in the construction;taking two double arch tunnel in Guilin for example,the author summarized longer connecting arch tunnel construction effect,the problems including the Earth Inclusion geology roof,roof problems,analysis of anchor force principle were solved,and the traditional construction technology was also optimized;the construction of the double arch tunnel construction technology for further optimization and improvement had completed the whole set process development it could provide the reference for the later similar project construction.
