人工挖孔桩基础%加固处理%承载力不足
人工挖孔樁基礎%加固處理%承載力不足
인공알공장기출%가고처리%승재력불족
随着国民经济的发展,各类民用与工业建筑日益走向高层化,人工挖孔桩以其特有的高承载力优势和操作工艺简单得到许多设计单位、施工单位的认可.但当人工挖孔桩深度较高,施工操作不当导致混凝土振捣不密实或者桩底沉渣过厚导致砼离析,混凝土强度及桩的承载力达不到设计要求,造成质量事故,最终需要对桩进行加固处理.本文结合重庆一工程实例,探讨人工挖孔桩基础加固设计方法基础事故处理中的应用.
隨著國民經濟的髮展,各類民用與工業建築日益走嚮高層化,人工挖孔樁以其特有的高承載力優勢和操作工藝簡單得到許多設計單位、施工單位的認可.但噹人工挖孔樁深度較高,施工操作不噹導緻混凝土振擣不密實或者樁底沉渣過厚導緻砼離析,混凝土彊度及樁的承載力達不到設計要求,造成質量事故,最終需要對樁進行加固處理.本文結閤重慶一工程實例,探討人工挖孔樁基礎加固設計方法基礎事故處理中的應用.

With the development of the national economy, various types of civil and industrial buildings increasingly high, artificial hole digging pile with its unique advantages of high bearing capacity and simple operation process have many desi-gn units, construction units acceptance.But when the manual hole digging pile construction of higher depth, due to improper operation of concrete vibrating imperfect or pile bot om sedim-ent is too thick to concrete segregation, the concrete strength and bearing capacity of pile is not up to the design requirem-ents, cause quality accident, eventual y the need for reinforce-ment of pile. Combined with the Chongqing engineering exa-mples,this paper explores on the application of hand-dug pile foundation reinforcement design method in basic incident handling.
