Advanced Drilling Exploration for Foundation Pile Engineering in Karst Region and the Optimization Design
Abstract:Foundation treatment is one of the most important steps in the power plant construction, and is also a basic work,especially in the karst region, where the geological conditions are more complicated. Analysis is made on the technical problems in the engineering pile construction of Hezhou power plant, according to the karst geological conditions of the corrosion belt, combined with the karst fissures, karst ditches, grooves and caves, the construction technical difficulties and measures are briefly analyzed.
