豫西北地区改性生土建筑材料抗压试验研究
|
摘要
在河南西北部山区农村生土建筑仍然存在,但建筑耐久性不够,主要针对豫西北地区农村仍在使用的生土建筑主要墙体材料———生土土料的受压性能进行试验研究.取豫西北地区素土、矿渣、石灰等为原材料,按照不同配比,分别制作素土、灰土和矿渣土试件.通过单轴压试验得到了试件的破坏形态、破坏过程、应力应变关系曲线;分析了影响生土结构土料抗压性能的主要因素,得出土矿渣、石灰等掺料能改善土料力学性能的结论,为生土建筑的墙体受力性能的研究提供了参考.
Adobe building is still used in partial countrysides of Henan Northwestern region,however,durability of house is not good.This article is a study on soil material about the compression performance of the main wall of adobe building used in countrysides of the region.According to various proportions of gangue and lime,pure soil specimens,gangue soil specimens and lime soil specimens are made of loess of the region.we obtained the specimen destruction shape,the destruction process,the stress-strain relations curve through the single axle pressure test,analyzed primary factor,analyzed primary factor compacting the compression resistance capabiloty of raus soit structure earth material,and got conclusions that the mechanical properties of soil material could omproved by mixing stay or lime.It provides reference for studying mechanical properties of the raw-soil wall body.
