Stratigraphic distribution of the piling area.

Number	Depth of the soil layer (m)	Cumulative depth (m)	Soil layer type
①	0.80–2.50	0.80–2.50	Plain fill
②	2.50–5.10	3.30–7.60	Loess-like soil
③	1.40–7.20	4.70–14.80	Mixed soil
④	0.00–3.20	4.70–18.00	Silty clay
⑤	2.50–2.80	7.20–20.8	Circular gravel
⑥	0.30–1.80	7.50–22.60	Highly weathered sandstone
