The design of the primary support of the largedeformation softrock section of Tongzhai tunnel on LanzhouChongqing railway is optimized on basis of studies on the deformation rules of the primary support in typical sections. Due to the optimization of the design, the concrete backfilling amount has been brought under effective control and the construction cost has been reduced.
