In this article, the author bases on the engineering example of Zhu Ling tunnel construction right line exports col-lapse in Ningji highway, analyzes the reasons of the tunnel col apse, sums up the lessons learned for the tunnel construct-ion in the bias of weak surrounding rock, and explores the pro-blem of half-dark into the tunnel hole when the terrain serious bias, and puts forward the program to provide theoretical supp-ort for the implementation of the project. At present, the tunnel entrance was safe and smoothly and the hole did not appear engineering disease.
