高液限黏土质砾承载比强度特性试验研究OA
Experimental Study on Strength Characteristics of the CBR of High Liquid Limit Clay Gravel
高液限黏土质砾属于非均匀、非均质、非连续的混合多相特殊地质材料,其承载比(CBR)强度特性较一般细粒黏土或粗粒填料有较大差异.因此,以我国西南地区某高速公路典型的高液限黏土质砾为研究对象,开展了不同含水率、不同细粒土含量和不同击实功下的CBR试验研究.其结果表明:高液限黏土质砾的CBR强度受颗粒组成、含水率和击实功等因素的综合影响,仅改变单一因素并不一定能提高CBR值;高液限黏土质砾的CBR强度变化比纯黏性土剧烈,受含水率影响更为明显;若不计算砾…查看全部>>
High liquid limit clay gravel belongs to heterogeneous,heterogeneous,and discontinuous mixed multi-phase special geological materials,and Califonia Bearing Ratio(CBR)strength characteristics are significantly differ-ent from those of general fine-grained clay or coarse-grained fillers.A typical high liquid limit clay gravel on a highway in the southwest region is taken as the research object.CBR experimental research were conducted with dif-ferent moisture c…查看全部>>
