摘要
为深入研究高层建筑施工中的深基坑作用力,设计一种新的高层建筑施工深基坑支护加固技术。基于支护作用确定加固沉降计算简图,在分析深基坑支护加固结构过程中,明确支护结构与深基坑接触的侧限压缩变形和正面冲击压缩变形是导致高层建筑深基坑沉降的主要因素,利用公式计算深基坑结构受到力的大小,结合计算结构,合理设计深基坑的支护结构,使支护结构的固定效果达到最佳。研究结果表明,设计的高层建筑施工中深基坑支护加固技术内部接头能够很好地处理刚度和接头之间的关系,减少形变量,确保加固效果。
In order to deeply study the force of deep foundation pit in high-rise building construction,a new deep foundation pit support and reinforcement technology in high-rise building construction was designed.The calculation diagram of reinforcement settlement was determined based on the support function.In the process of analyzing the support and reinforcement structure of deep foundation pit,the main forming factors of lateral compression deformation and frontal impact compression deformation of the contact between the support structure and deep foundation pit were clarified.A series of calculation formulas were used to calculate the force on the deep foundation pit structure,and the support structure of deep foundation pit was reasonably designed in combination with the calculation structure.The fixing effect of the supporting structure will be the best.The results show that the designed internal joint of deep foundation pit support and reinforcement technology in highrise building construction can well deal with the relationship between stiffness and joint,reduce shape variables and ensure the reinforcement effect.
