摘　　要：提出一种软土地区暗挖技术——对拉技术,用于中短距离的地下管涵及通道。无支座反力;施工面不失压;行程减半;两个施工面;拉索导向。该技术在国内首次成功应用于综合管沟下穿昆玉高速段工程。The directional mutual pull technology,a trenchless technology suitable for soft ground,is suitable for the construction of short and middle distance,straight underground passage and culvert.It features with:supporting force free,without pressure in working surface,reduction of half distance,two working surfaces,and steel cable as guidance.This technology is first successfully used in the engineering prac- tice of Kunming common utility duct (underpassing Kunyu Expressway),which was built by this con- struction technology.
