摘要
充填体结构对其承载能力起到重要作用。通过对灰石配比为1∶0,1∶2,1∶3,1∶4,1∶5与1∶6的6组块石胶结充填体试件进行单调加载与分级加载下的压缩试验分析,得出块石胶结充填体抗压强度随块石占比变化的一般规律,发现不同加载方式下灰石比1∶2的充填体试件抗压强度和平均单位能耗均大于其余各组试件,而灰石比1∶5试件抗压强度与破坏能耗均与配比为1∶2的试件接近。
The structure of filling body had an important in- fluence on the bearing capacity. The compression tests on six groups of cemented rock filling body with cement-rock ratio of 1 ： 0, 1 ： 2, 1 ： 3, 1 ： 4, 1 ： 5 and 1 ： 6 were respective- ly conducted and analyzed under monotonic loading and step loading. It obtained a general rule that the compressive strength of cemented filling body changed with different con- tents of rock. The compressive strength and average destruc- tive energy dissipation of filling body with cement-rock ratio of 1 ： 2 was larger than the othersr under different stress paths, which was close to the test specimen with cement- rock ratio of 1 ： 5.
