The closed ring confining truss is set along the periphery of the reticulated shell, and the stiffening truss is set in the middle single-layer shell which can take advantage of the architectural shape. These measures resolve the contradiction between overall stability and temperature stress, and also avoid the shell thrust act on the lower concrete structure directly. Besides, these measures simplify the design of the shell bearing and the concrete structure, and the cost of the concrete structure can also be saved.

In responding to the problems identified, a countermeasure of bolt-mesh-anchor-shotcrete + floor-bolt + truss coupling supporting is proposed, namely using shotcrete to seal surrounding rock, bolt-mesh support to release deformation energy, floor bolt to transfer floor heave plastic slippage force, anchor-truss support to control the deformation of surrounding rock. Therefore, the effective deformation control of deep high stressed soft rock roadway can be achieved.
