Embodiment Construction

[0041] On the basis of the prior art, the present invention further considers the individual characteristics of different arch dams, different dam sections of the same arch dam, and different elevations of the same dam section. Highly personalized controls. The specific method can be implemented according to the following steps (such as figure 1 ):

[0042](1) In order to realize the analysis of individualized cantilever height control by dam section and elevation, for a certain extra-high arch dam, each different dam section i (i=1, m, m is the dam section number), according to different The joint grouting process n (n represents the completed joint grouting in the grouting area and below) is divided into different working conditions step i j (j=1,n).

[0043] (2) For each working condition step i j , using the three-dimensional finite element method, according to the proposed super-high arch dam construction organization plan, simulate the gradual superposition of temp...

Abstract

The invention discloses a personalized control method for cantilever height of an ultra-high arch dam, and relates to a personalized control method for the cantilever height of a concrete arch dam by utilizing a three-dimensional numerical method for solving and guiding and considering the actual construction requirement. The personality characteristics of different arch dams, different dam sections of the same arch dam and different elevations of the same dam section are further considered on the basis of the prior art, so that personalized control over the cantilever height of the ultra-high arch dam is realized by a three-dimensional finite element method. By the control method, the construction progress is accelerated, so that the construction period of the high dam is further shortened, and key objectives such as dam body water blocking and flood protection and expected power generation are achieved on schedule.

Description

technical field [0001] The invention relates to a method for controlling the cantilever height of an extra-high arch dam in a hydraulic structure, in particular to an individualized control and analysis method for the cantilever height of an extra-high arch dam. Background technique [0002] At present, in the southwestern region of my country, many 300m-level super-high concrete arch dams are being constructed vigorously, which has also brought many new problems that need to be solved urgently. Among them, the cantilever height control during the construction period has become one of the key issues in the construction of ultra-high arch dams. [0003] During the construction period of high arch dams, several transverse joints are generally set up in adjacent dam sections, and the dam body is divided into columnar pouring blocks. When the dam body cools to the specified temperature, the joints are grouted, so that the dam is formed as a whole. Before the transverse joints a...
