Embodiment Construction

[0056] The arch dam pouring block masonry method comprises the following steps: a, first carry out arch dam shape parameter curve fitting, wherein the control parameters of the arch crown beam section are the upstream dam surface curve of the arch crown beam and the thickness Tc of the arch crown beam, the horizontal arch The control parameters of the ring are the X and Y coordinates of the arch end, the curvature radius R of the arch ring and the central angle:

[0057] (1) Parameter fitting of arch crown beam:

[0058] The curve of the upstream dam surface of the crown beam and the thickness Tc of the crown beam at any point along the elevation are fitted by cubic curve interpolation, and the fitting formula is:

[0059] T c (z)=t 0 +t 1 *z+t 2 *z 2 +t 3 *z 3

[0060] A u (z)=a 0 +a 1 *z+a 2 *z 2 +a 3 *z 3

[0061] In the formula, A u (z) - the distance from the upstream surface point of each calculated elevation arch crown section to the dam axis;

Abstract

The invention relates to an arch dam construction control method, and belongs to the field of water conservancy and hydropower, in particular to an arch dam pouring block construction control method. According to the technical problems, the arch dam pouring block construction control method can fast and accurately determine space parameters of arch dam pouring blocks, so that arch dam structural construction is completed. The arch dam pouring block construction control method comprises the following steps that a, firstly arch dam shape parameter curve fitting is carried out; b, secondly, arch dam shape coordinate calculation is carried out; c, a coordinate formula of an intersection of a lead straight surface and upstream surface and downstream surface of an arch ring is established; d, the lowest point coordinates of the upstream surface of the lead straight surface after corner cut of the upstream surface are calculated; and e, finally by using the parameters obtained through the steps, the parameters are converted to a CAD graph through a DXF file, a plane graph, a radial profile graph and an arch dam three-dimensional shape graph of arch dam pouring block points are obtained, and construction operation is carried out through obtained structural information. The arch dam pouring block construction control method is especially suitable for water and electricity large dam arch dam pouring block construction.

Description

technical field [0001] The invention relates to an arch dam construction control method in the field of water conservancy and hydropower, in particular to a construction control method for arch dam pouring blocks. Background technique [0002] The rich dam-building experience accumulated by the predecessors and the development of science and technology have made the arch dam line shape more and more diverse. The parabolic arch has been widely used in my country in recent years because of its characteristics such as easy selection of parameters, strong ability to adapt to river valleys, and good stress conditions. The Xiluodu project under construction also uses the parabolic arch as the recommended dam shape. [0003] The basic method of arch dam shape design is to first determine the control elevation, draw up the arch crown section and the geometric shape of the control arch ring according to the terrain, geological conditions and hub layout of the dam site, and then deter...
