Abstract:: A power plant in Henan is a key project of the country’s "July 5th", and the original ground is ups and downs. In order to transform the complex and changeable adverse conditions of the original landform, the landfill is used. In order to improve the physics of the soil layer, the bearing capacity of the foundation increases the foundation, and eliminates the wetness of the I -level non -self -wet trap. This article introduces the basic points of the project’s strong decaying design, and the detection method of ramming effects, and analyzes the mechanism formed by the ground -strong support layer (ultra -hard soil layer) and eliminates the dampness of loessing. It is proven through a variety of testing methods, and the advantages of reinforcement to reinforcement to reinforcement are effective, low cost, and fast speed. It is a reasonable reinforcement measure.
