Abstract:

The landsonar is presented in this paper, which is based on the principle of elastic reflection wave and is a method of geological forecasting in tunnel construction. Due to the light instrument and simple operation, the landsonar is widely used. The landsonar has been successfully used to forecast karst caves and faults in more than 20 cases. And the fourthgeneration landsonar LDS3 has been put into production.

Key words:  , Landsonar elastic wave eflection tunnel geological forecasting
