拱坝坝肩开挖及地基处理措施研究

结合实际工程，对天花板拱坝的坝肩开挖及地基处理措施进行了研究，根据实际地质情况提出了坝基开挖、固结灌浆、接触灌浆、帷幕灌浆、基础排水、断层破碎带处理和岸坡锚固支护等措施，以使坝基满足稳定、应力、变形、抗渗和耐久性等各方面的要求。

Study on abutment excavation and foundation treatment measures of arch dam

Combined with the practical engineering,the paper studies the abutment excavation and the foundation treatment measures of the Tianhuaban arch dam,puts forward the measures of the dam foundation excavation,the consolidation grouting,the contact grouting,the curtain grouting,the foundation drainage,the fault crushed zone treatment and the bank slope anchorage support based on the practical geological condition,to make the dam foundation meet the requirement of the stability,the stress,the deformation,the impermeability and the durability.
