Table 9

Calculation comparison of test groups 34.

	Test	a①	b①	c①	d①	b②
1	−136.6	−77.2	−75.6	−75.1	−110.8	−85.3
2	130.7	183.1	139.3	154.4	88.6	148.1
3	−78.3	−77.2	−75.6	−75.1	−110.8	−85.3
4	88.5	58.2	58.6	57.5	−3.8	89.2

Note: the equivalent blasting load is 260 kN; the lateral resistance force is 20 kN/m.
