Summary of the corresponding depth of the maximum bending moment of the suspended foot connecting wall.

Working procedure	Suspended foot diaphragm wall (west, the length is 45.82 m)		Suspended foot diaphragm wall (east, the length is 51.98 m)
	Maximum bending moment (kN∙m/m)	The depth of the diaphragm wall (m)	Maximum bending moment (kN∙m/m)	The depth of the diaphragm wall (m)
The first excavation (−2.000 m)	383.553/−154.641	−34.37/−43.53	495.496/−183.378	−38.99/−49.38
The third excavation (−13.400 m)	732.862/−311.066	−27.49/−43.53	1127.781/−404.225	−20.79/−49.38
The fifth excavation (−24.550 m)	2080.852/−600.905	−34.37/−43.53	3621.628/−1118.857	−33.79/−49.38
The seventh excavation (−34.145 m)	2654.072/−250.395	−34.37/−43.53	4654.927/−1193.643	−38.99/−49.38
The tenth excavation (−51.630 m)	2596.608/−469.726	−34.37/−43.53	4251.651/−42.949	−38.99/−51.98
Remarks	Among the maximum bending moments in the table, the maximum positive bending moment value is before “/” and the maximum negative bending moment value is after “/,” respectively, corresponding to the depth of the diaphragm wall.
