Abstract
Based on the multi-factor surrounding rock pressure calculation theory, the values of surrounding rock pressure and construction safety and stability coefficients corresponding to different construction methods required by engineering design and construction could be quickly and conveniently calculated with the derived general formula, so as to guide and optimize the design and construction scheme. In this paper, the influence of lateral load coefficient on surrounding rock pressure was analyzed and verified, and the calculation method and application range of lateral load coefficient were proposed. Meanwhile, according to the multi-factor surrounding rock pressure calculation theory, an arched precast member was proposed, which was assembled into an optimal and reasonable honeycomb-like stress structure, and applied in the support of tunnel and underground space. It could improve the construction technology of composite lining by taking the advantage of the common load bearing of surrounding rock and support. In addition, with the theory, the application of arched precast member in the support of deep foundation pit has simplified the setting of lateral support of deep foundation pit in the horizontal direction, which is an innovative construction method for deep foundation pit support using prefabricated assembly components. Certainly, the calculation theory should be further studied, and the dynamic change of surrounding rock pressure after excavation under various adverse geological conditions should be accurately analyzed and verified by means of monitoring and measurement, which should be reasonably connected with the current Code for popularization and application. It is hoped that the study of the calculation theory and its application in engineering practice can provide useful guidance and help for the design and construction of tunnel and underground space.
