Abstract

The invention relates to a form-variable stilling basin front end energy dissipation structure and an energy dissipation method thereof. The form-variable stilling basin front end energy dissipation structure is mainly composed of a WES overflow weir and a stilling basin, wherein the WES overflow weir comprises a curve section of the WES overflow weir, a linear section of the WES overflow weir andan inverted arc section of the WES overflow weir; the stilling basin comprises a stilling basin front end, a stilling basin rear end and other parts. Innovation is conducted mainly aiming to high intensity of pressure of the stilling basin front end, the stilling basin front end is divided into blocks with same size, and accessory hydraulic jacking devices are arranged on the stilling basin bottom plate blocks obtained through dividing respectively; the relative height between each stilling basin bottom plate block and the inverted arc section of the WES overflow weir is adjusted through accessory hydraulic control valves; in order to bring convenience to actual management of engineering, a main hydraulic control valve is installed, and the whole device can be adjusted.

Description

technical field

[0001] The invention relates to a modified form stilling pool front end energy dissipation structure and an energy dissipation method thereof, belonging to the field of flood discharge and energy dissipation of hydraulic structures in water conservancy and hydropower projects. Background technique

[0002] In the design of dam engineering, flood discharge and energy dissipation are the two major tasks undertaken by the discharge structure, that is, to safely discharge excess flood water while strictly controlling the erosion of the dam body and downstream foundation pit by the discharge flow to prevent damage to the dam body and instability of the dam foundation . Especially for flood discharge projects with high water head and large flow, there are problems such as large flow velocity and pulsating pressure at the bottom of the bottom plate, high difficulty in anti-shock protection, large size of stilling basin required, and high cost. Therefore, research on...
