It is equal to design value times γ, which is the resistance partial coefficient of material, taking 1.1 for steel. pb is the compressive bearing capacity of joint plate, which also is got by design value multiplying γ.
The strength ratio of I-type SEP is 41.5%, indicating the material behavior of bolts group and joint plate are not reached greatly.

Research on the Prevention of Shaft Lining Fracturing in the Special Strata Based on the Monitoring Information Pengli He1, 2, a Cuiran Liu 2, b 1School of Civil Engineering Xi’an University Architecture and Technology China 2Department of Civil Engineering Luoyang Institute of Science and Technology China ahepengli2003@126.com bliucuiran@163.com Key words: shaft lining fracturing, grouting reinforcement, vertical addition force, monitoring information Abstract: The method of cement grouting in surrounding soil can be used to fundamentally prevent and cure the shaft lining rapture by its dual effects of release and restraint vertical addition force.
Grouting materials for cement slurry and fly ash, the mixture ratio for: water: cement: fly ash: J85 accelerating agent= 0.7: 0.25:0.75: 0.025.
