Abstract: Research in this paper is expected to further reveal the behaviors of soil nailing by field test, so as to provide scientific basis for its broad application. Some field tests, including measurements of horizontal displacement, nail force and et al., of a soil nailed project are described and comprehensive analyses of the results are given. The behaviors of soil nailed structures both in construction phase and in service phase are further investigated based on the measurements. Useful suggestions are proposed for its design and construction.
