Excavation Type Optimization of High Cutting Slope at Reservoir Bank
Because our country is a mountainous country, in engineering construction process, inevitably involve a lot of high cutting slopes. Summarized the relevant research achievements of predecessors, we put forward the type optimization scheme based on the current problems of smaller longitudinal slope degrees at bottom interface of high cutting slopes. Setting some slower longitudinal slope degrees at the bottom interface of high cutting slopes, which will reduce excavation volume to a certain degree, thus reduce energy consumption, reduce the influence of excavation on the surrounding environment, and reduce relevant expenses to restore the slope environment. After setting some slower longitudinal slope degrees, the slope toe drainage will be more unobstructed, the slope height will be reduced, and the slope will be more stable, thus reduce the work amount of slope retaining. For each year, thousands of kilometers mountainous highway will be built, bottom interface type optimization of high cutting slopes will have very big economic value. Therefore, which is worth to recommend in construction and designing of high cutting slopes.
