Three-consecutive-arc design method for pipe-type culvert section

Abstract

The invention relates to a three-consecutive-arc design method for a pipe-type culvert section. The method is used for acquiring geometric parameters of an inner contour line of the pipe-type culvertsection. The method comprises the steps that (1) a design benchmark of the inner contour line of the culvert section is determined; (2) a basic control parameter A and a basic shaping parameter U of design of the inner contour line of the culvert section are determined; (3) an association mode between the parameters A and U and the inner contour line of the culvert section is determined, and a three-consecutive-arc design model of the pipe-type culvert section is established; and (4) cyclic correction is performed on the basic shaping parameter U according to the three-consecutive-arc design model of the pipe-type culvert section till the requirement of the basic control parameter A is met. Compared with the prior art, the method has the advantages of precise design, normalized design steps, standardization, etc.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to a three-arc design method for the section of a tubular culvert. Background technique [0002] Culverts are an important component of civil engineering, and are widely used at home and abroad to connect water systems on both sides of routes. At present, the common problems in culvert construction are as follows: [0003] 1. The size design of the structure is unreasonable, the construction materials are wasteful, and the single cost index remains high; [0004] 2. There are defects in standardization and systematization. After adopting prefabricated structures, it often becomes an additional burden on construction; [0005] 3. The effect of scale and industrialization is not good, and it often falls into the embarrassing situation of high technology but high cost; [0006] 4. The design is not uniform and there are many structural forms. It has become a top priority t...
