The geological behaviors of wet outflow deposition fly ash were investigated, including the feature of in-situ single and even bridge cone penetration test (CPT) curves, the change of the penetration parameters and vane strength with the increase of depth and the difference of the penetration resistance on and down the water level. Drilling, CPT and vane shear test were carried out in silty clay, fine sand, and fly ash of the ash-dam. The CPT curves of the fly ash do not show a critical depth. The cone resi... 相似文献

在山坡沟谷处,由于第四系地层成因复杂,如风化、坡积、洪积和冲积等,层厚差异可能较大,宜通过钻探揭露深部土层情况,切不可盲目臆断。结果表明,修建石拱涵时,先要详细掌握地层情况,合理设计,规范施工。结果可供相似工程借鉴。 相似文献
