摘要
Abstract
Lufeng Nuclear Power Plant is located in Jieshi Town,Shanwei City,Guangdong Province.The plant site is situated in a border area between sea and land,with complex geological conditions and the presence of spherical weathered bodies in the geological strata.During the construction process of the foundation pit enclosure structure,the presence of spherical weathered bodies makes it difficult to form drilled piles,often resulting in deviated holes,which seriously restricts the progress of the project.By using pre blasting methods to create cracks in isolated rocks and inclined rock layers,drilling efficiency can be improved and engineering progress can be accelerated.关键词
