Vibration-Isolation Performance of a Pile Barrier in an Area of Soft Soil in Shanghai

Table 1

Positions of measurement points in the first group of tests.

GI	GI-1	GI-2	GI-3	GI-4
Distance between measuring point and hard-X-ray tunnel (m)	92	221	305	368
Buried depth (m)	0	0	0	0

Note: the measurement points are used to collect the vibration accelerations as follows: ground traffic on Luoshan Road (GI-1); traffic on Luoshan Road viaduct (GI-2); maglev (GI-3); metro line 16 (viaduct part) (GI-4).
