Prediction of Response of Existing Building Piles to Adjacent Deep Excavation in Soft Clay

Table 3

Observed soil surface settlements at measuring points of Fengqi Road excavation.

Measuring points	M6	M7	M8	M9	M10	M11	M12	M13	M14	M15	M16
Distance from corner	0	13.17	27.05	40.81	56.54	56.31	50.09	42.4	25.05	10.82	−0.59
Observed settlement value (mm)	13.6	18.8	24.6	28.8	34	25	23.5	21.9	18.6	16.7	15.4

The southwest corner of the excavation serves as the reference point. The positive distance value indicates that the measuring point is located at the east side of the corner of excavation, and the negative value indicates that the measuring point is located at the west side of the corner of excavation. The specific layout of the measurement points is shown in Figure 9.
