国民经济的快速持续发展,建筑工程的大量开展,必然要设计到很多深基坑工程,而双排桩支护结构在深基坑工程中得到了日益广泛的应用。所以非常有必要对深基坑双排桩支护结构的设计计算方法进行研究。本文在对前人成果进行了一定的分析总计,并对其进行借鉴,从双排桩前后排桩排距的不同所造成作用效应模式的不同这一点出发,将双排桩的作用效应分为三种情况进行相应的设计计算,提出了一些设计计算的思路,并对提出了一定的计算公式,以期能够有助于深基坑双排桩支护结构设计计算方法研究。
The rapid and sustained development of the national economy, construction of a large number of projects, will inevitably have to design a lot of deep foundation pit project, and double-row piles support structure in the deep foundation pit project has been more widely used. Therefore, it is very necessary to study the design and calculation method of double-row piles supporting structure in deep foundation pit. In this paper, some achievements of predecessors were analyzed and summed up. Based on the difference of effect effect patterns caused by the different row spacing of double row piles, the effect of double row piles was divided into Three cases of the corresponding design and calculation, put forward some ideas of design and calculation, and put forward a certain formula, in order to be able to contribute to deep excavation double-row piles retaining structure design and calculation methods.
