Calculation comparison of test groups 6.

	Test	a①	b①	c①	d①	b②
1	369.5	218.5	355.0	395.5	472.9	371.6
2	−121.7	−271.9	−177.2	−175.8	−181.4	−195.2
3	122.8	3.2	171.2	168.6	170.2	213.1
4	−134.7	−271.9	−177.2	−175.8	−181.4	−195.2

Note: the equivalent blasting load is 700 kN; the lateral resistance force is 84 kN/m.
