藏族民居砌体材料物理力学性能试验研究

选取阿坝藏族自治州理县境内的黄泥与石材,参考国家标准试验方法,进行黄泥与石材物理力学性能试验研究,将试验结果与数值分析结果进行对比。结果表明:黄泥土粒主要由砂粒组成,级配良好;黄泥抗压强度为0.408 MPa,弹性模量为231 MPa,石材抗压强度为67.92 MPa;黄泥砂浆弹性阶段承载力模拟值略高于试验值,但极限承载力基本保持一致,石材弹性阶段与弹塑性阶段模拟值均与试验值保持一致,数值分析结果与试验结果吻合较好。试验研究结果可为砌体材料力学性能数值分析方法提供理论基础。

Experiment Research of Stone Masonry Materials Physical Mechanic Property of Tibetan Folk House

Experimental study on physical and mechanical properties of yellow mud and stone is performed by selecting a large yellow mud and stone in the aba Tibetan autonomous prefecture, and according to the national standard test method, and the experiment resualt is compared with numerical analysis. It turned out that yellow mud is mainly composed of sand grain, well graded, compressive strength is 0.408 MPa, Elastic modulus is 231 MPa, The compressive strength of stone material is 67.92 MPa; The results of numerical analysis results agree well with the test results. Bearing capacity of yellow slurry elastic stage simulation value is slightly higher than the experimental values. But the ultimate bearing capacity is basic consistent. Stone material is elastic and elastic-plastic stage simulation values are consistent with the test results. This research results provide theoretical basis for numerical analysis of masonry material mechanics performance.
