Calculation comparison of test groups 4.

	Test	a①	b①	c①	d①	b②
1	255.2	148.3	254.8	286.3	346.8	273.1
2	−93.7	−184.7	−110.7	−109.8	−114.1	−131.0
3	77.6	−45.9	85.3	83.0	84.4	149.7
4	−81.9	−184.7	−110.7	−109.8	−114.1	−131.0

Note: the equivalent blasting load is 546 kN; the lateral resistance force is 84 kN/m.
