ABSTRACT

Matrix transfer method is a structural analysis method between force method and displacement method. Because the calculation process is multiple multiplication of a series of lower order matrices, it is a kind of high precision and simple method, through programming, can obtain accurate results. At present, some scholars applied the transfer matrix method to concrete structure analysis. Literature[7] detailed discusses the application of matrix transfer method in a variety of engineering structures; In Literature[8], the matrix calculation method of anti-slide pile is deduced by using the initial parameter method; Literature[9-13] put the matrix transfer method used in structural analysis of the curved bridge; Literature[14] put the matrix transfer method used in the static analysis of steel bridge structure, four kinds of representative bridge are chosen as the research object, and

1 INTRODUCTION

When tunnel lining is under greater surrounding rock pressure on the vertical and horizontal directions, often using curved-wall type tunnel lining[1]. At present the analysis calculation of the internal force of tunnel lining often adopt load structure method and layer structure method[2,3]. The layer structure method considered the interaction of structure and surrounding strata, can more realistically simulate the structural internal force of the underground structure and deformation of surrounding strata under every single construction Step. But due to the complexity of the surrounding strata and the interaction between formation and structure, layer structure method is in the development stage, in many engineering applications, just as a supplementary means[4,5]. Load structure method based on the mechanics principle, not considering the interaction of the structure and the formation. In load structure method, often using force method and displacement method which are only applicable to solve the problems that calculation diagram is relatively rough, the number of unknowns is not too much in structure analysis[6].
