Problems solved by technology

However, the water flow control plan must rely on limited temperature measuring points to formulate. When the temperature of the measuring points cannot reflect the actual temperature information in a larger range inside the dam block or some special circumstances, the cooling water flow control plan for the dam block lack of effectiveness

Embodiment Construction

[0026] 1. Model establishment: For a single dam block 1.1, its internal temperature field is greatly affected by the upper and lower adjacent dam blocks, but limited by the left and right bank adjacent dam blocks. Consider respectively integrating the adjacent upper dam block 1.2 and lower dam block 1.3 to form the target dam block model 1. Such as figure 1 shown. Since the thickness of the dam block is small relative to its horizontal dimension, it can be regarded as a thin plate body. Then for any single dam block 1.1, its three-dimensional temperature field is greatly affected by the upper dam block 1.2 and lower dam block 1.3 of the same dam section, but is limited by the adjacent dam blocks on the left and right banks. Under the condition that there is no temperature measuring point on the contact surface of the upper dam block 1.2 and the lower dam block 1.3, if the upper dam block 1.2 and the lower dam block 1.3 are not considered, then the single dam block 1.1 will ...

Abstract

The invention discloses a concrete temperature field simulating calculation method based on a pouring block. As for a single dam block, a part of an upper dam block and a part of a lower dam block are combined into the single dam block to form a target dam block model, wherein the upper dam block and the lower dam block are adjacent to the single dam block; grid joints around a cooling water pipe are arranged in the radial direction of the cooling water pipe, the grid units gradually become larger from the position close to the water pipe to the position far away from the water pipe. The plane temperature field simulation is achieved. According to the concrete temperature field simulating calculation method based on the pouring block, temperature simulation is carried out on the pouring block, and the temperature field data of the whole pouring block are obtained. Individuation water passing suggestions are given for specific situations, the control level for cooling water passing is improved, and therefore the construction quality of dam concrete is improved, and the workload of site constructors is relieved.

Description

technical field [0001] The invention discloses a concrete temperature field simulation calculation method based on pouring blocks, which is used in the field of temperature control of pouring blocks. Background technique [0002] Hydraulic concrete buildings are generally large in size, and due to construction and structural needs, they are often poured in large volumes. During the hydration and hardening process of the cement in the concrete, a considerable amount of hydration heat will occur, so that the internal temperature of the concrete will rise rapidly within a few days after pouring, and the temperature will begin to drop when it reaches the highest temperature. But because concrete is a material with extremely poor thermal conductivity, if it is allowed to dissipate naturally, sometimes it will take ten years or even hundreds of years for the temperature inside the dam body to reach a stable temperature. From the point of view of the requirement of benefiting from...
