The invention discloses a method for drawing a foundation pit excavation drawing. The method comprises the following steps: step 1, according to a basic plane drawing of a building, applying building information model software to establishment of a foundation pit mass model, and enabling the foundation pit mass model to be consistent with the design dimension proportion in the basic plane drawing; step 2, laying off on the foundation pit mass model according to the building construction drawing, and forming an excavation model; step 3, applying the software to creation of a two-dimensional foundation pit excavation drawing according to the excavation model; step 4, based on the two-dimensional foundation pit excavation drawing, carrying out foundation pit excavation, and meanwhile, utilizing the three-dimensional foundation pit mass model to assist understanding and review. The method, disclosed by the invention, can effectively solve the problem that the excavation drawing is difficult to draw because when a large-scale foundation pit is excavated, the location and lay-out is complicated; compared with the regular drawing method for the excavation drawing, the method can greatly reduce drawing workload and drawing time to shorten the work period; compared with the regular excavation drawing, in the exported excavation drawing, size marking is realized via the software automatically, so that the phenomena of marking missing and mis-marking can be greatly reduced, and the drawing is high in accuracy.

The invention discloses an accelerated corrosion testing method for simulating a soil corrosion process. The method comprises the following steps of: (1) preparing a testing solution from salt and water according to components of target soil; (2) adjusting the pH (Potential of Hydrogen) value of the testing solution to a testing value by H2SO4 or NaOH, thus taking the testing solution as an impregnation medium for simulating soil corrosion, wherein the testing value is the same as the pH value of the target soil; (3) mixing diatomite, which is taken as a carrier, with an impregnation medium to prepare testing soil which is basically same as the target soil in physicochemical properties; and (4) testing a test sample in the testing soil according a pre-set testing temperature, relative humidity and testing period.

The invention provides a method for evaluating the permeating performance of a chemical imbibition agent. According to the evaluation method, the elevating coefficient Sc and permeation speed Sp of a capillary can be measured, thus the permeation force Fp can be calculate according to a formula: Fp=Sc*Sp; the performance of a chemical imbibition agent can be evaluated through a ratio (R) of the permeation force Fp of a chemical imbibition agent to a simulated water permeation force, and if the R is greater than 1.0, the chemical imbibition agent has a good imbibition effect. The method can be used to quantitatively evaluate the permeating performance of a chemical imbibition agent for low permeability reservoir. The method has the advantages that the indoor tests become convenient and fast, the comparison and quantitation become more convenient; the permeating performance and diffusion property of different chemical imbibition agents can be effectively compared; corresponding oil sand and capillary that are similar to oil reservoirs are used to simulate the oil reservoirs, at the same time, the experiment temperature is identical with the temperature of stratum, and thus the experiment is closer to the actual state.
