摘要
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。
The forming cause, forming structural profile,chemical composition,mineral constituents and important physical properties(grain size distribution, Atterberg limits, compaction property etc.)of soils in the Huanhe delta region are discussed in this paper. The problems of road diseases, lime stabilization and lime-flyash stabilization in terms of the foregoing properties of soils are analysed. The feasible methods for increasing the strengths of soil-lime and lime-flyash soil in accordance with the clay mineral contents, colloidal activity and adsorptive action of soils are put forward as well.
