充填体结构对其承栽能力起到重要作用。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栽下的压缩试验分析,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,发现不同加栽方式下灰石比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.
