“…The convenience of the simulation calculation provides technical support for further exploring the influence of soil factors such as the elastic modulus, cohesion and internal friction angle on a pile row system [18]. This makes it possible to optimize and adjust design parameters, such as the pile spacing, number, buried length and pile type [19][20][21][22], and especially a sensitivity analysis under the interaction of multiple factors [23][24][25].…”

The theoretical calculation of a counterweight double-row pile supporting structure is deduced and studied in this paper. The derived calculation method is applied to a Midas GTS NX simulation calculation. A case study of a deep foundation pit project in Shenzhen City is used to verify and analyze the simulation results and the field monitoring results. On this basis, the influence law of deformation parameters such as the row distance, pile diameter of back-row piles and load of the pit top on the pile of a double-row pile is further discussed. The results show that both the front- and back-row piles of counterweight double-row piles are overturning deformation, and the characteristics of the horizontal displacement are basically the same. The maximum value of the horizontal displacement of the pile is at the top and the minimum value is at the bottom. With the increase in the row distance and pile diameter, the horizontal displacement of the pile becomes smaller, and the change in the pile horizontal displacement under a top load is contrary to that. Moreover, the change in the row distance has a great influence on the horizontal displacement of the pile, followed by the load of the pit top, and the pile diameter of the back-row piles has the least influence. Due to the connection effect of the horizontal plate of the counterweight platform, the whole supporting structure is in the form of a hyperstatic structure. The back-row piles can withstand most of the lateral earth pressure, which effectively reduces the deformation of the front pile and improves the overall stiffness of the supporting structure, which is conducive to the excavation stability of the deep foundation pit. Therefore, its extensive use in the Linhai soft soil project can not only effectively reduce the number of internal supports and achieve the purpose of cost saving but also increase the construction face, which is beneficial to the development of dry construction organization and management, in line with the construction concept of green environmental protection and sustainable development advocated at present.

“…In recent years, research on double-row pile supporting structures has achieved significant results. For example: (1) The control effect of the pile diameter, the pile length, the crown beam, the connecting beam, and other basic structural dimensions, as well as pile spacing and row spacing, on the horizontal deformation and vertical settlement of the whole double-row pile structure system and the cost control of foundation pit engineering [26][27][28][29][30]; (2) The influence of the development of the soil arch effect on the deformation of the doublerow pile supporting structure during the excavation of the foundation pit [31][32][33]; (3) Based on the numerical simulation analysis, the deformation mechanism and deformation characteristics of the overall double-row pile structure, the front pile, the back pile, the crown beam, the connecting beam, etc. [34][35][36]; (4) Optimization and innovation of the pile-soil interaction calculation model [37][38][39][40].…”

“…When it is far away from this node, the supporting effect of the double-row pile supporting structure will not only be greatly reduced but also increase the project cost in terms of cost control [41][42][43][44]. For example, Wang et al [29] found through numerical modeling that the control effect of a double-row pile supporting structure on the stability of the foundation pit is similar to that of a single-row pile when the spacing of the double-row pile supporting structure is too small. Appropriately increasing the double-row pile gap can have a good control effect on reducing the level shift of the supporting structure.…”

The conventional support forms of foundation pit retaining piles include single-row piles, double-row piles, anchor-row piles, and so on. The double-row pile supporting structure is widely used in the deep foundation pit supporting the engineering of wharves, bridges, subways, tunnels, and high-rise and super-high-rise buildings. This study on double-row pile supporting structures mainly focuses on four aspects: (1) The influence of dimension parameters, such as pile diameter and pile length, and engineering parameters, such as pile spacing and row spacing, on the deformation control of a double-row pile structure and the stability control of foundation pits; (2) Influence of the soil arch effect on the stress and deformation of the double-row pile supporting structure; (3) Study on the deformation characteristics and rules of the components and the whole structure of the double-row pile supporting structure; (4) Study on the calculation model of pile-soil interactions. Based on the above four aspects, this paper summarizes the latest research status of the existing double-row pile supporting structure and its stress and deformation characteristics. The deformation characteristics and calculation model of the pile-soil interaction of double-row piles are reviewed and evaluated. Finally, the problems and deficiencies in the research on double-row pile support are summarized. These results provide a reference for future research on the double-row pile supporting structure of the foundation pit and the numerical analysis and calculation model and lay a solid foundation for further development of the theory.
