Meanwhile, there are few combinations of theoretical research and concrete planned projects, and even less pattern theory of Low-slope hilly development and urban construction supported by engineering practice.
Low-slope hilly development and utilization should actualize three-dimension connotations: ecological safety, engineering economy and social equity.
Achieve Engineering Economy through Dynamic Correction Assessment Unit.
Among them, amount of excavation in unit area is the major engineering economic index, and decides the whole cost of development.
