Embodiment Construction

[0020] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0021] The demonstration analysis and foundation treatment method for nuclear power plants with vertical weak interlayer foundations provided by the invention includes site survey, dynamic calculation analysis, static calculation analysis, and foundation treatment scheme. On-site investigation is geotechnical engineering investigation and test carried out on the construction site of the nuclear power plant. It should be able to obtain the dynamic and static physical and mechanical parameters of various materials in the foundation (including bedrock, weak interlayer, etc.). The dynamic calculation analysis is used to calculate the influence of the existence of the vertical weak interlayer on the response spectrum of the engineering site, and the amplified response spectrum is used as the seismic input of the structural design. The static calculation an...

Abstract

The invention relates to a method for foundation treatment and argument and analysis of a vertical weak intercalated layer foundation in a nuclear power plant. The method includes on-the-spot investigation, dynamic calculation analysis, static calculation analysis and foundation treatment scheme. By means of calculation and analysis, a vertical weak intercalated layer in a certain depth is replaced by concrete. The method has the advantages that adaptability of the power plant to nonuniform foundations is improved, flexibility in selection of a nuclear power plant address is improved, selection period of the nuclear power plant address is shortened to some extent, engineering construction cost is lowered, and competitiveness in the nuclear power industry is promoted.

Description

technical field [0001] The invention relates to an analysis and treatment method of uneven foundation, in particular to a demonstration analysis and foundation treatment method of a nuclear power plant containing a vertical weak interlayer foundation. Background technique [0002] Nuclear power plants have high safety requirements for foundations. The foundations of nuclear power plants at home and abroad are generally homogeneous and hard rocks, and the uneven foundations encountered by nuclear power plants are basically horizontal layered foundations. [0003] For the case of vertical weak interlayers in the foundation of nuclear power plants, there are few domestic engineering practices at present, and traditional analysis methods cannot be used for such foundations, and the influence of vertical weak interlayers on the superstructure cannot be obtained more accurately, nor can it be guaranteed The rationality of the ground treatment plan.
