Coal gangue is a kind of mining waste, one has the largest emissions and depositions in mining resources exploitation, almost accounts for 1/4 of the national industrial waste residue emissions. Through load test, we do a research on allowable bearing cap%煤矸石是我国在矿业资源开采中排放及积存量最大、占用堆积场地最多的矿业废弃物，约占全国工业废渣排放量的1／4，通过载荷试验，对煤矸石容许承载力与变形模量进行研究，进而探讨其作为建筑地基的可行性，为煤矸石的利用提供相关依据。
