摘　　要：简要地介绍引兰入汤工程隧洞设计情况。该隧洞采用弧线型布置，在隧洞经过的沟谷部位设置３条施工支洞。隧洞为无压洞，断面按通过最大流量设计，断面型式为圆拱直墙式，坡降为１／１０００。该设计采用了新奥法。The paper briefly introduces the design of tunnel at the project diverting water from Lanhe River to Tanghe River. The tunnel plan layout is curved. There are three construction drifts at the gully passed by the tunnel. The tunnel is one of free flow, the cross section is designed a circular arch and vertical wall according to pass maximum discharge, the slope gradient is 1/1000. The support design adopts New Austrian method and makes a simple analysis of the different adjoining rock.
