【Abstract】 Project practice shows that for the contact grouting between the penstock and concrete of a hydropower project,there exist some problems at the stages of penstock design,construction and operation,which will have an impact on project quality and construction progress,even threaten the project safety.Based on practice experience and relative project data,the paper analyzes and discusses the above problems from different aspects,classifies the fissures between penstock and concrete,and gives recommendations about the design and construction of contact grouting,making a reference for the industry.更多还原
