Problems solved by technology

The structural calculation of the box culvert body is an important part of the engineering design work. Considering the complexity of the structural calculation, especially for the three-hole box culvert, it will consume a lot of manpower and time to calculate it manually; The external force and internal stress borne by the box culvert group are in a "black box" state, it is difficult to know the health of the box culvert group's structural state, and it is difficult to judge and warn of safety risks

As long as the basic data is input into the computer, the calculation result will be obtained immediately, the calculation workload is reduced, and the design efficiency is increased by more than 120%. .

[0130] Combine below image 3 with Figure 4 The specific implementation steps in the design phase are as follows:

[0131] (1) Calculate the unit stiffness of each member according to the actual three-hole box culvert, and input the unit stiffness to Figure 4 Middle ① unit stiffness parameter input area;

[0132] (2) Calculate the fixed end bending moment according to the actual load of the three-hole box culvert, and input the calculation result of th...

Embodiment 2

[0137] A long-distance water transfer project is 35km long, and there are 121 three-hole box culverts, forming a box culvert group. In the operation stage, the present invention can effectively monitor the health status of the entire engineering box culvert group, and provide a basis for early warning of safety risks. Combine below figure 2 with image 3 The specific implementation steps in the operation phase are as follows:

[0138] (1) During the construction of each three-hole box culvert, earth pressure sensors are pre-embedded at the junctions of side walls and roofs, middle walls and roofs, side walls and low plates, and middle walls and bottom plates. The specific positions are as follows image 3 The numbers 1 to 12 in the middle;

[0139] (2) In the operation stage, the pressure sensing unit of each box culvert integrates and transmits the data monitored by the sensor through the industrial computer of the data transmission unit, and sends it to the data processi...

Abstract

The invention discloses a three-hole box culvert group internal force analysis method suitable for a long-distance water conveyance project. The invention comprises a monitoring system and an analysis system; the monitoring system comprises a pressure sensing unit, a data transmission unit and a data processing and analyzing unit, the pressure sensing unit and the data transmission unit are deployed on each box culvert site, and the box culvert group of the whole long-distance water conveyance project shares one data processing and analyzing unit; and the pressure sensing unit is connected with the data transmission unit in a wired mode, and the data transmission unit transmits data of the pressure sensing unit to the data processing and analyzing unit and the like through the Internet or a local area network. In the operation stage of the box culvert project, the external force and internal stress state borne by the box culvert group of the whole long-distance water conveyance project can be effectively monitored, the load change of the cross project in the long-distance water conveyance project can be quickly responded, the structural health state of the box culvert group in the operation period can be conveniently judged, and a foundation is provided for safety risk early warning.

Description

technical field [0001] The invention belongs to the design technical field of water delivery and supply projects, in particular to a method for analyzing the internal force of a three-hole box culvert group suitable for long-distance water delivery projects. Background technique [0002] Long-distance water transmission projects refer to construction projects that use pipelines to transport raw water and clean water with a water transmission distance of more than 10km. With the continuous development of urbanization in our country, the urban water demand is increasing year by year, and the long-distance water transmission project is an effective measure to solve the rapid increase of urban water consumption. Box culverts are often set up when long-distance water transmission projects pass through obstacles such as rivers, valleys, hills, roads, and railways. Box culverts are a type of hole structure layout of culverts, and are generally cast-in-place integrated reinforced co...
