The method comprises steps of temperature field finite element analogue simulation being conducted by means of surrounding rock, lining concrete thermal parameters, actually-measured in-tunnel temperature data and lining concrete construction data of each type of target engineering; carrying out finite element stress analogue simulation; establishing a correlation model of lining concrete internal and external temperature gradient and cooling rate of each type of target engineering and lining ultimate stress; determining concrete allowable stress according to the cracking risk criterion; determining the highest temperature, the internal and externaltemperature gradient and the cooling rate control standard of the lining concrete based on the correlation model and the concrete allowable stress; and performing temperature control on the lining concrete by utilizing an intelligent gradient temperature control system based on the maximum temperature of the lining concrete, the internal and external temperature gradient and the cooling rate control standard; and the temperature control anti-cracking of the lining concrete construction in the whole period being realized.

Description

technical field [0001] The embodiments of the present application relate to the technical field of construction engineering, and in particular to an intelligent gradient temperature control method, system, device and readable storage medium. Background technique [0002] The spillway tunnel is an important water release structure in water conservancy and hydropower projects, which is used to release the water volume of the upstream reservoir to ensure the safety of the water retaining structure when encountering a flood. When the spillway tunnel is in operation, the water flow has a high velocity. In order to reduce the adverse effects of high-speed water flow on the stability of the surrounding rock of the spillway tunnel and the safety of the chamber, the spillway tunnel is generally supported by concrete lining. On the one hand, the concrete lining of the spillway tunnel can strengthen the surrounding rock and bear the load of the surrounding rock to ensure the safety of ...

Problems solved by technology

[0004] In actual engineering, the temperature, humidity, and wind speed in the tunnel are constantly changing with the closure of the main tunnel or branch tunnel. Under certain uncontrollable construction factors such as construction equipment entering the tunnel, concrete transportation, etc., the tunnel must be opened for a long time , the temperature, humidity, and wind speed in the cave may change drastically, and the designed constant flow and water temperature are still used for artificial water control. The temperature control index of the lining concrete may no longer meet the control standards, and the risk of lining cracking may also increase.
