Subsidence analysis map of Xianhe town. (a) Enlarged plot of settlement rate. AA′ and BB′ are profile lines, the black and yellow lines are Shugang expressway, and the areas with subsidence rates greater than −300 mm/a, −250 mm/a, and −150 mm/a are denoted by red, green, and blue vectors, respectively. (b) The vector denotes the range of cumulative subsidence greater than 20 mm (with reference to 10 January 2018). The vectors of brown, dark green, purple, and light green are the cumulative subsidence in February 15, April 10, August 14, and December 24. (c) Profile maps based on AA′ and BB′. (d) The fitted line of the distance between the subsidence boundary and the Shugang expressway and month.
