通过击实试验和击实后土样的压缩和剪切试验研究红黏土的变形和强度特性。研究表明:重塑土的最大干密度比原状土的最大干密度大,而重塑土的最优含水率则比原状土的最优含水率小;随击实功增大,土样的干密度增大,而最优含水率减小;含水率稍高的击实土样的水稳定性要比含水率稍低的击实土样的水稳定性好;当含水率较大时,击实土样的相对固结变形量较大,固结稳定并浸水再固结后,原来含水率较小土样的变形增量反而稍微大些。
The deformation and strength characteristics of red clay were studied by compaction and compaction tests. The results show that the maximum dry density of remolded soil is larger than the maximum dry density of undisturbed soil, while the optimum moisture content of remolded soil is smaller than that of undisturbed soil. The density increased, and the optimal water content decreased. The water stability of compacted soil samples with slightly higher water content was better than that of compacted soil samples with lower moisture content. When the moisture content was higher, The relative solidification of real soil-like deformation is large, solidification and stability after immersion and consolidation, the original soil moisture content of smaller deformation increases but slightly larger.
