Building materials laboratory was established in 1956. Due to the relocation of the school several times in the last century, the experimental equipment was seriously damaged, and few experiments could be carried out. Although the school invested some experimental equipment in the 1980s, it only completed some experimental teaching courses. Based on the principle of more lectures and less experiments, experimental teaching barely lasted for many years. This also seriously affects the quality of experimental teaching, making students' hands-on ability poor, and affecting the knowledge mastery and understanding ability of theoretical courses.
200 1 With the establishment of the Institute of Water Conservancy and Architecture and the vigorous development of water conservancy in China, the experimental funds given by the school to the Institute of Water Conservancy and Architecture have also increased year by year, and experiments can be set up even if they have not been available for many years. And increase the experimental hours, expand the experimental projects, purchase domestic advanced experimental equipment, and lay a good foundation for the society to cultivate applied talents. At present, the laboratory area is 240.02 square meters, and there are 106 sets of equipment, totaling about 3 10/0,000 yuan. The experimental items are: cement setting time and cement stability (check whether cement quality is qualified), cement mortar strength and cement fineness (check whether cement strength and cement quality are qualified), fine aggregate analysis (check sand gradation), coarse aggregate analysis (gravel gradation), concrete mix design (design concrete strength and workability), mortar mix design (design mortar strength and bleeding), sand apparent density and sand accumulation density (service concrete quality). The Soil Mechanics Laboratory undertakes experimental courses for five majors, namely, agricultural hydraulic engineering, water conservancy and hydropower engineering, civil engineering, project management and landscape, with an average of 120 class hours per year, which is about 12 class hours. There are five experiments: soil water content and density experiment, soil liquid plastic limit experiment, soil particle size analysis, soil compaction experiment, soil compression experiment, soil shear experiment and soil triaxial demonstration. The existing laboratory building area is 140m2. 96 sets of equipment, totaling 365,438+0,000 yuan.
At present, the experimental course "Water Content and Density of Soil" is set up to understand the density and dry-wet state of soil and get the corresponding parameters. "Joint test of liquid-plastic limit of soil" is to find out the liquid-plastic limit, and get the plasticity index and compressibility index, which can be used as the classification of cohesive soil and the estimation of foundation soil bearing capacity. "Compaction experiment of soil" uses a hammer to increase the density of soil. Under a certain compaction effect, the density will be different with different water content. Determining the maximum dry density and optimum water content of excavated soil under standard compaction method is an important index to control the compaction degree of filled soil foundation. "Soil compression experiment" measures the compression deformation of soil samples under various pressures, calculates the void ratio of soil samples under a certain load, draws a compression curve, and calculates the unearthed compression coefficient and compression modulus. "Shear strength test of soil" measures the shear strength of soil and calculates the basic indexes (internal friction angle and cohesion) used for foundation strength and stability. Soil mechanics experiment is an applied experiment, which requires strong hands-on ability, that is, to obtain data through hands-on experiments in the future, to obtain results through theoretical calculation and to solve practical problems.
