Abstract
This paper proposes construction technology and quality control of soil and rock mixed fill subgrade for soft soil roads in response to the shortcomings of low compaction and large settlement deformation in the construction of soft soil roadbeds with high moisture content.According to the geological structure design of the specific road construction plan,the soil properties and ground bearing capacity of the area are surveyed and the location for the construction of the road trunk line is selected.Key parameters such as support points,slope lines and roadbed elevations are measured;sample labels are placed;the quality of the soft soil is analysed;appropriate soil and rock materials are selected;and the ratio of the soil-rock mixture is optimized.Following drainage consolidation,the subgrade material is filled in layers and compacted,and a cement mixing pile is employed for grouting and reinforcement purposes,thereby reducing porosity and enhancing the strength and stability of the structure.Following settlement detection and verification,the deformation settlement of the engineering subgrade is controlled to within 2 mm and the compaction degree reaches over 90%,providing good structural stability.关键词
