Abstract
Micro-pile is a kind of small diameter bored piles, also known as root pile, pile diameter is generally 150-400mm, length-diameter ratio is generally greater than 30,and pile length is usually not more than 30m. Compared with ordinary pile, micro-pile has the advantages of fast construction speed, small working surface, high bearing capacity and small settlement.
Highlights
Optimization of micro-pile foundation structureThe optimization of the foundation structure firstly establishes the miniature pile foundation solid model of the tower foundation through the finite element numerical simulation software ANSYS WORKBENCH, and verifies the effectiveness of the design by applying load

Micro-pile group commonly used in transmission line engineering has four pile caps and nine pile caps foundation, and its plane schematic diagram is shown in Figure 1(a)(b) respectively
Summary
The optimization of the foundation structure firstly establishes the miniature pile foundation solid model of the tower foundation through the finite element numerical simulation software ANSYS WORKBENCH, and verifies the effectiveness of the design by applying load. Micro-pile group commonly used in transmission line engineering has four pile caps and nine pile caps foundation, and its plane schematic diagram is shown in Figure 1(a)(b) respectively. The finite element numerical simulation software ANSYS WORKBENCH was used to establish the solid model of the mini pile nine pile cap and the four pile cap foundation of the tower foundation, as shown in Figure 2 and Figure 3 respectively:. Applying the foundation force of 2e3-sjc, the stress and strain distribution cloud diagram of the four pile caps foundation is shown in figure 4-4.
