本文系统论述了黄河三角洲地区土的成因，土的成型构造剖面，化学组分，矿物组成特点及土的重要物理特性：颗粒分布、可塑性界限含水量、击实特性。依据土的上述特性，分析了道路病害、单纯石灰稳定、石灰与粉煤灰等综合稳定的问题。依据土的粘土矿物含量、胶体活性和吸附作用，提出了适宜提高石灰土、二灰土强度的可行方法。
This paper systematically discusses the origin of the soil in the Yellow River Delta, the tectonic profile of the soil, the chemical composition, the mineral composition characteristics and the important physical characteristics of the soil: particle distribution, plastic limit moisture content and compaction characteristics. According to the above characteristics of soil, the problems of road disease, simple lime stability, comprehensive stability of lime and fly ash are analyzed. Based on the clay mineral content, colloidal activity and adsorption of soil, a feasible method suitable for increasing the strength of limestone and lime-soils is proposed.
