Research on calculation metheods of earth pressure on muti-arch tunnel for highway
摘要
Abstract
IN light of the present situation without mature formulations to calculate the loading of multi-arch tunnel for highway in China, the formulation of the earth pressure is derived based on the loading feature of multi-arch tunnel and PU'S equilibrium arch theories. Considering the division altitude of deep tunnel and shallow tunnel specified in the tunnel code, the division altitude and the loading formulation are proposed. Thus a fully calculation system is formed here. Lots of analyses and calculations validate that the formulation presented is reasonable by comparing with other formulations. Good effects are achieved when applying this formulation in the design of both multi-arch tunnel and bifurcation tunnel for the highway from Shanghai to Chengdu.关键词
