本文将建筑废料用于改良湿陷性黄土地基。为了研究改良地基土的相关力学分布规律。先进行压实特性试验,将一定天然含水量为12%的湿陷性黄土与建筑废弃物拌合,通过对比不同掺量不同击实次数的湿密度随击实次数的变化情况,确定最佳击实次数为45次。在最佳击实次数条件下,制备高为152mm、直径为116mm的标准试样,进行单轴压缩试验。综合对比无侧限抗压强度与弹性模量二个力学参数,最终确定最优配合比为15%。
In this paper, construction waste is used to improve collapsible loess foundation. In order to study the laws of distribution of the improved mechanics of foundation soil. Compaction characteristics of the first test, the natural moisture content of 12% of the collapsible loess and construction waste mixed by comparing the different dosage of different compaction times the wet density with the number of changes in the actual situation to determine the best The number of compilation 45 times. Under the optimum number of compaction times, a standard specimen with a height of 152 mm and a diameter of 116 mm was prepared and subjected to a uniaxial compression test. Comparing the two mechanical parameters of unconfined compressive strength and elastic modulus, the optimal ratio is 15%.
