Problems solved by technology

However, the diversion system of high arch dam construction is affected by many random factors such as hydrology and hydraulics, so there are risks involved. In the design of diversion engineering, the risk analysis method based on probability theory must be used to reasonably consider the influence of these random factors.

Embodiment

[0089] Taking the implementation of a high arch dam project in the upper reaches of the Jinsha River as an example, the dam type is a concrete double-curvature arch dam, and the maximum dam height is 217.0m. The hub building consists of three major systems: a concrete double-curvature arch dam, flood discharge and energy dissipation buildings, and water diversion and power generation buildings. The hub project is a first-class large (1) project, using a city gate-type diversion tunnel, and its operation runs through the initial-middle stage of construction. The initial diversion standard adopts the 20-year flood standard, and the medium-term diversion standard adopts the 100-year flood standard.

[0090] The optimization design steps are as follows:

[0091] 1. Based on the mathematical model for the optimal design of the diversion tunnel size of high arch dams, the constraints data are given:

[0092] The initial diversion standard adopts the 20-year flood standard, and the...

Abstract

The invention relates to the diversion optimization design technology of construction of hydraulic and hydroelectric engineering and discloses an optimization design method of a diversion tunnel of ahigh arch dam, which features that the investment of diversion project is reduce, the construction period is shortened and the safety of flood season is ensured. The method includes the following steps: a, constructing a mathematical model of diversion tunnel size optimization design of high arch dam; b, initially setting that size of the diversion tunnel of the high arch dam; c, obtaining that dynamic simulation results of the whole dam body of the high arch dam in each month and the joint grout elevation; d, adjusting and optimizing the diversion tunnel size of high arch dam. The high arch dam diversion tunnel size optimization design scheme of the invention reduces the investment of the diversion project, shortens the project time limit, and is suitable for the high arch dam hydropowerproject.

Description

technical field [0001] The invention relates to the optimal design technology of water conservancy and hydropower engineering construction diversion, in particular to the optimal design method of the size of diversion tunnels of high arch dams. Background technique [0002] A number of high arch dam projects over 200m in southwest China, such as Baihetan, Wudongde, Yebatan, Mengdigou, Maji, etc., are under construction or planning and design. higher requirements. Most of these high arch dams are located in deep mountains and canyons in the southwestern region, where the construction floods have a large fluctuation and the construction environment is relatively harsh. The construction diversion design and decision-making are closely related to the construction appearance of the dam body. The engineering practice of arch dams shows that the operation of the diversion tunnel often runs through the diversion stage in the early-middle stage of construction, and its design obviou...
