In the embodiment, by taking the stable stress calculation of the flood discharge gate on the bottom plate at the parting position as an example, the efficient and accurate calculation result is obtained by modeling through a model and a load and using a method for calculating the stable stress through parameters.
As shown in fig. 1 to fig. 10, the calculation method process and the screenshot of the operation interface in the CATIA in this embodiment are shown, and the tree diagram in the screenshot is not completely displayed due to the overlong characters, but does not affect understanding of the technical solution in this embodiment.
As shown in fig. 1 and 2, a sluice model and a load model in the method for computing sluice stress stability analysis based on CATIA of the present invention are shown, wherein:
fig. 1 depicts a sluice model consisting of a pier model 1, a floor model 2 and a sluice model 3.

The method for analyzing the stress stability of the sluice based on the CATIA calculation in the embodiment is carried out according to the following steps:
the first step is as follows: relevant stress stability analysis calculation parameters such as upstream and downstream water levels, sediment volume weight, shear-resistant friction coefficient, shear-resistant cohesive force and the like (which are standard parameters) are established through CATIA user parameters, specifically, the analysis calculation parameters are divided into necessary parameters and optional parameters, the necessary parameters comprise parameters related to the water gate body type (used for adjusting the water gate body type, such as the length of a water gate pier, the thickness of a bottom plate, the position of a gate, the thickness of the water gate pier, the length and the width of the bottom plate, the width of an upstream grouting platform and the like, namely, parameters affecting the larger body type, and parameters affecting the smaller body type, such as the size parameters of a gate slot, which only affect the small dead weight and do not have large influence on other load action positions and sizes), and parameters related to the upstream and downstream water levels under different working conditions, and establishing a base surface geological parameter, a sediment parameter, a seismic parameter and a uplift pressure parameter. The optional parameters include wind load parameters, wave load parameters, soil pressure, etc. The parameters such as the wind load parameter and the wave load parameter are generally small in load and small in influence on the scheme, the parameters are calculated by using a traditional empirical formula, manual loading can be carried out after table calculation, calculation can also be carried out in CATIA (computer-aided three-dimensional interactive application), modeling is complex, and the soil pressure parameter can be selected and used as required; as shown in fig. 6, initial calculation parameters include upstream water level to overflow surface, downstream water level to overflow surface, chamber length, foundation bottom surface length, chamber width, chamber overflow surface clear width, allowable bearing capacity, geological parameter f (corresponding to shear-resistant friction coefficient), geological parameter c (corresponding to shear-resistant adhesive coefficient), uplift pressure reduction coefficient, gravitational acceleration, silt internal friction angle, silt floating volume weight, upstream overhaul gate, working gate, downstream overhaul gate, working door machine, downstream gate slot, working gate slot, and the like (see table 1 below specifically), and the model body shape adjustment and stable stress parameter calculation are controlled by the parameters;
TABLE 1
The second step is that: establishing a sluice model by loading an existing sluice model template in the CATIA or directly modeling in the CATIA; the CATIA software has a template establishing function, can load a designed sluice model template from an existing sluice database, and can also establish a new sluice model template according to the use requirement, wherein the existing sluice model in the figure 1 is directly loaded from the sluice database;

The total load magnitude values are: ρ gh × h × 0.5 × a — ρ gh × h × 0.5 × h × b. According to the load calculation condition, triangular load distribution is converted into a volume model, namely a triangular prism, along the width of a water gate, a triangular prism load model is established as the volume model of water thrust in the CATIA modeling process, and the height of the triangular section of the triangular prism is as follows: ρ gh × h × h, the bottom is h, the height of the cylinder is b (water gate water retaining width), and the volume of the triangular prism is: 0.5 × height × base × column height ═ ρ gh × h × 0.5 × h × b (equal to the load value), and similar derivation and conversion may be performed for other loads.
