What are the characteristics of earthwork construction and the requirements for organizing construction?

The characteristics of earthwork construction are: large amount of work, many mechanical equipment, great influence by seasons, complex construction conditions, and obvious influence on ecological environment and geological and hydrological conditions;

The requirements for organizing the construction are: organizing the implementation of the test section, summarizing and determining the loose paving coefficient, rolling technology, rolling equipment combination and earthwork volume per unit area, detecting the soil source, ensuring that CBR, liquid plastic limit, maximum dry density, optimal water content and organic matter content meet the requirements of the specification, and compiling the construction scheme, transportation scheme, foundation pit excavation scheme, support scheme, precipitation scheme and monitoring scheme.
