摘 要:采用煤矸石与生石灰、粉煤灰按照合适配合比制成混合料(即煤矸石二灰混合料),并用该种混合料进行地基换填,经过养护后利用平板载荷试验,测出了该混合料的p-s曲线、s-lgt曲线,得出了地基承载力特征值及变形模量。研究表明,该混合料的地基承载力很高,变形模量也较高,可用作20层以下建筑的地基换填处理材料。 Abstract:Coal gangue, lime and fly ash are mixed according to appropriate mix proportion. Using the mixture to replace the foundation, and using the plate loading test after the curing, the p-s curve, s-lgt curve of the mixture are tested, and the characteristic value of subgrade bearing capacity and deformation modulus are concluded. The research shows that the subgrade bearing capacity of the mixture is very high and the deformation modulus of the mixture is higher as well, which can be used as the foundation replacement material for the buildings below 20 floors.
