Zusammenfassung:On the construction of tunneling method for poor soil conditions, nowadays the long-fore-piling method is generally employed as a auxiliary construction method to secure a stability of tunnel facing and prevent a ground settlement. But the effective mechanism of this method has not been solved yet. This paper describes some considerations on the effects of AGF (All Ground Fasten) method; one of the long-fore-piling method, by refering to construction records, indoor model experimental data and monitoring data in four construction fields.
