Determination of Embedded Depth of Soldier Piles in Pile-Anchor Supporting System in Granite Residual Soil Area

Table 3

The steps of test preparation.

Step	Test preparation
1	Install displacement sensor and keep the vertical distance of the displacement monitoring points behind the pile with interval of 12.5 cm.
2	Install earth pressure cell according to the location of the waist beams.
3	Preembedded piles and anchor rods. Prebury the soil to the corresponding height, install the anchor rod, and fix it with screws until the excavation reaches the corresponding position to simulate the actual anchor rod construction stage.
4	The dial indicators were set on the soil surface after the soil is filled and compacted.
5	The physical model after the completion of embedded work is shown in Figure 7.
