Study on Reasonable Application of Base-grouting Bored Concrete Pile and PHC Pipe Pile Works

The base-grouting treatment technique of bored concrete pile can improve the bearing capacity and PHC pipe pile can lower the engineering cost,thus the application of tow kinds of pile become broad day by day.But,there are many factors arrecting pile foundation selection for construction works.Through the cost analysis and evaluation on the pile foundation of the typical works,the some economic indicators for the selection of pile foundation under the present productive force and price level are gained.Which will be beneficial to improve the cost effetiveness and rationality of selection of it.
