A method of dynamically controlling the anti-floating process of basement construction based on bim technology

Abstract

The invention is a method for dynamically controlling the anti-floating of the basement construction process based on BIM technology, which belongs to the field of building anti-floating technology. Aiming at the problem that the existing method cannot save energy consumption and ensure the safety of the basement construction process at the same time, the technical scheme is as follows: a method based on The method of BIM technology to dynamically control the anti-floating process of the basement construction process includes the following steps: Step 1, establish a BIM parametric model; Step 2, generate a 4DBIM model, and obtain the curve of the upper load changing with time; Step 3, input the upper load and groundwater level The relationship or curve of the groundwater level and the relationship or curve of the groundwater level changing with time; Step 4, calculate the maximum water level control curve that changes with the upper load; Step 5, detect the groundwater level; Step 6, when the groundwater level at a certain moment When the value exceeds or is equal to the value corresponding to the dynamic alarm value curve at the same moment, the control water level is within the safe range. The method of the invention saves energy consumption and ensures the safety of the basement construction process.

Description

technical field [0001] The invention belongs to the field of building anti-floating technology, in particular to a method for dynamically controlling the anti-floating process of a basement construction process based on BIM technology. Background technique [0002] With the continuous increase of urban land value and the improvement of underground space construction technology, builders pay more and more attention to the development and utilization of underground space. Deep foundation pits exceeding 10 meters are common in big cities, and deep foundation pits exceeding 20 meters are also It is no longer a novelty, and there are even ultra-deep foundation pit projects exceeding 30 meters. Precipitation is an important measure to ensure the smooth progress and safety of earth excavation during deep foundation excavation, but reasonable control of precipitation is often neglected during the gradual construction of basement structures and main structures. There are two common ...
