长沙有色冶金勘察公司在多年工作的基础上,并广泛收集利用了兄弟单位的资料,提出了《湖南花斑红土的工程地质特性和地基评价研究报告》(向春尧)。该报告较系统地阐述了湖南在花斑红土的时代成因、地理分布、埋藏条件、岩性特征、物质成分和物理力学性质,提出了该土是个独立的区域性工程地质地层单元的认识;以一定数量的压板试验和建筑物沉降长期观测资料为依据,建立了适用该土的新的容许承载力表和变形模量经验数据表,其平均 Based on many years of work, Changsha Non-ferrous Metallurgical Investigation Company has extensively collected and used data from its fraternal units and put forward the “Research Report on the Engineering Geological Characteristics and Foundation Evaluation of Hunan Freckle Red Clay” (Xian Chunyu). The report systematically elaborated the causes, geographical distribution, burial conditions, lithology, material composition, and physico-mechanical properties of Hunan in the variegated red soil, and proposed that the soil is an independent regional engineering geology and stratum unit; Based on a certain number of plate tests and long-term observations of building settlement, a new allowable bearing capacity table and empirical data table of deformation modulus for the soil were established and averaged.
