中文摘要：

制备不同水灰比的水泥砂浆试件、不同配合比的掺煤渣水泥砂浆试件、不同置入方式的掺铁丝水泥砂浆试件、不同掺入量的掺玻璃纤维水泥砂浆试件以及风化片麻岩试件,试验得到了其单轴抗压强度等力学指标。泰山区域的片麻岩试样分别隶属于未风化、中等风化、强风化和全风化4种风化程度。掺骨料水泥砂浆试件的强度不能达到中等风化程度片麻岩的强度,掺煤渣水泥砂浆不能作为强风化或全风化片麻岩的强度置换材料。掺铁丝七组和掺玻璃纤维六组水泥砂浆试件的抗压强度超过了20MPa,是强风化或全风化片麻岩地基处理的理想置换材料,尤其掺铁丝E组水泥砂浆试件的铁丝掺量、横/竖铁丝置入方式及其对应的基准配合比（C：S：W）1.00：3.95：0.68是推荐的,掺玻璃纤维D、E组水泥砂浆试件的玻璃纤维掺入质量比0、2‰和4‰及其对应的基准配合比1.00：4.29：0.74和1.00：3.95：0.68是科学合理的。注入掺骨料水泥砂浆是提高风化片麻岩地基工程稳定性的有效途径,亦是合理的地基置换材料,变形控制是风化片麻岩建筑地基设计时需要重点考虑的因素。

英文摘要：

Specimens of cement mortar blending aggregate have been prepared by varied ratios of water and cement,different proportions of mixed cinder.changed posting modes of iron wire and several blend ratios of glass fibre,to receive their mechanical parameters of uniaxial compressive strength and ultimate strain by test.According to the same testing results gneisses on study may be subjected to the non- weathered,middle weathering,strong weathering and full weathering respectively.Strengths of all cement mortar specimens blending aggregate do not arrive at that of middle weathered gneiss,so cement mortar mixed cinder can not substitute for strong or full weathered gneiss.There are seven cement mortar specimens posted iron wire and six cement mortar specimens blended glass fibre which may be by way of ideal material to substitute for foundation of strong or full weathered gneiss,for their strengths have all been beyond20 MPa.Especially group E of cement mortar specimens posted iron wire their quantity,horizontal and upright modes of iron wire and corresponding proportion of mixture（C：S：W） 1.00：3.95：0.68 are recommendatory.Meanwhile group D and group E of cement mortar specimens blended glass fibre are reasonable material whose quality ratios of blended glass fibre are 0,2‰ and 4‰,and basic proportions of mixture are 1.00：4.29：0.74 and 1.00：3.95：0.68.Cement mortar blending aggregate should be an available approach to enhance engineering stability of weathered gneiss and sound substituted material for foundation.That is,controlling deformation of the weathered gneiss is a determined factor for foundation design.
