The bedrock surface protruding is an important problem to be solved in the construction of rail transit. High density resistivity method was applied in the abnormal area of bedrock protrusions in the Xiamen rail transit investigation project. The two-dimensional electrical structure of the surveyed area is obtained by data processing and inversion analysis of the field data. The distribution area of bedrock protrusion is deduced and the protrusions in interpreted after the cross analysis of two-dimensional electrical structure characteristics and the regional geological conditions. Some investigation results are obtained.The survey results are verified by drilling and they are consistent with the drilling geological data up to81% which provide a basis for the design works. The application of high density electrical method to identify the geological phenomenon of bedrock is worthy to promote.
