Problems solved by technology
Although this method has been greatly improved, there are still flaws. The decimal point of the data obtained through the calculation draft has precision requirements, and the problem that the coordinates of the obtained spatial points do not overlap always exists.
Moreover, the amount of calculation is large, there are many coordinate control points, and the calculation is time-consuming and labor-intensive.
[0003] In comparison, it is faster, more efficient, and more precise to construct the panel plinth structure with the help of geometric composition and 3D modeling by setting preconditions. However, no similar scheme has been found in the prior art.

Embodiment Construction
[0017] The present invention will be described in detail below with reference to the drawings and embodiments.
[0018] like Figure 1-4 Shown, the present invention implements according to the following steps:
[0019] 1. Analyze the plinth structure of the panel and determine the construction edge:
[0020] The spatial structure of the face plate and plinth of the face rockfill dam is complex, but after careful analysis, there are still rules to follow. General structure of plinth see figure 1 :
[0021] Plinth structure conventional such as figure 1 As shown, the toe plate of the complex point also includes the inner toe plate. Regardless of the plinth structure, it is determined figure 1 The space section shape of the toe plate, the additional inner toe plate can be added according to the design needs, so the discussion of the inner toe plate is not of universal significance, so it is determined figure 1 The space section of the plinth shown is sufficient.

The invention discloses a method for integrating design of a concrete face toe plate structure of a rockfill concrete face dam, which comprises the following steps: S1, analyzing the structure of theconcrete face toe plate and determining a key edge; 2, making the key edges of the toe plate by a geometric method; 3, stretching the toe plate; S4, cutting the toe plate; S5, after the defect angle of the toe plate is manually treated and the panel is stretched; S6, X line development drawing of the toe plate. The invention realizes the construction of the three-dimensional model of the face slaband the toe slab of the rockfill concrete face dam through the geometric composition method. Specifically, we only need to know the slope ratio of the panel, the thickness of the panel, the thicknessof each section of the toe board, the width of the toe board bottom and the T-line layout of the horizontal plane, and realize the integrated three-dimensional design of the toe board of the panel through the geometrical method. Moreover, the invention discards the traditional method of calculating the key point coordinates of the panel and the toe plate through the complex operation of excel, soas to obtain the three-dimensional model of the panel toe plate quickly, efficiently and with zero error.
Description
technical field [0001] The invention relates to an integrated design method for a face plate plinth structure of a rockfill face dam, which belongs to the technical field of water conservancy and hydropower engineering. technical background [0002] There are many studies on the structural design of face dams. Most of them determine the space angle between the facing surface of the face plate and the horizontal line on the cross-section of the plinth according to the "Hydraulic Design Manual". Although this method has been greatly improved, there are still flaws. The decimal points of the data obtained through calculation drafts have precision requirements, and the problem that the coordinates of the obtained spatial points do not overlap always exists. Moreover, the amount of calculation is large, and there are many coordinate control points, and the calculation is time-consuming and labor-intensive. [0003] In comparison, it is faster, more efficient, and more accurate t...
