Abstract：Research purposes: In the construction of the Baiyun Tunnel of the Nanning － Guangzhou Railway，the small mud bursting appeared in faultand and the large － scale mud and water bursting happened to cause the casualties and disaster when clearing silt．
Research conclusions: ( 1) The advanced geological forecast is an effective means of prevention of mud and water bursting，so it must be done in construction． When the mud burst happens，the evaluation must be done for the risk of cleaning silt，otherwise it is dangerous． ( 2) The grouting method was successfully used for treatment of the dyke of the mud and water bursting and for construction of the tunnel in the fault fracture zone safely． The treatment of the fault fracture zone of the tunnel was conducted by taking the technique measures of piling broken stones for protection，circuitous construction and treatment of main tunnel，and it would be as the reference to the similar engineering．
