Embodiment 1
[0096] figure 1 For the flow chart of the method for obtaining the earth pressure of the limited soil body considering the width of the earth in the adjacent underground engineering according to the present invention, the following will refer to figure 1 , a detailed description of the method for obtaining the limited soil earth pressure of the present invention that considers the width of the separation soil in the adjacent underground engineering.
[0097] First, in step 101, the design parameters of the foundation pit, the surface load parameters, and the physical and mechanical parameters of the rock and soil mass are determined.
[0098] In the embodiment of the present invention, the design parameters of the foundation pit are determined by the design scheme, including the width S of the intermediate soil and the depth H of the foundation pit under the current excavation process.
[0099] In the embodiment of the present invention, the surface load parameter is the over...
Embodiment 2
[0178] figure 2 It is a schematic diagram of the earth pressure calculation model of the finite soil body with intermediate soil according to the present invention, such as figure 2 As shown in the figure, under the condition of the existence of intermediate soil with limited width, the excavation construction on both sides of the foundation pit is performed simultaneously, and the earth pressure under active and passive conditions is only provided by the intermediate soil of half the width. During active failure, the soil is displaced toward the inside of the foundation pit, and the virtual velocity on the fracture surface is at a certain angle to the fracture surface and points to the side of the foundation pit. During passive failure, the soil body is displaced away from the foundation pit, and the virtual velocity on the fracture surface is at a certain angle to the fracture surface and faces away from the foundation pit.
[0179] In the embodiment of the present invent...
Embodiment 3
[0182] Embodiments of the present invention also provide an electronic device, Figure 4 It is a schematic structural diagram of an electronic device according to the present invention, such as Figure 4 As shown, the electronic device 40 of the present invention includes a processor 401 and a memory 402, wherein,
[0183] The memory 402 stores a computer program, and when the computer program is read and executed by the processor 401 , the computer program executes the steps in the above-mentioned embodiment of the method for obtaining the limited soil mass and earth pressure considering the width of the partition in the adjacent subterranean project.
