Calculation comparison of test groups 4.

	Test	a①	b①	c①	d①	b②
1	−144.2	−227.4	−223.4	−222.2	−311.4	−247.5
2	380.5	484.8	375.3	412.9	248.5	397.2
3	−189	−227.4	−223.4	−222.2	−311.4	−247.5
4	181.9	172.5	173.4	170.9	17.4	250.1

Note: the equivalent blasting load is 650 kN; the lateral resistance force is 20 kN/m.
