Abstract:	摘要： AbstractTime domain reflectometry (TDR) has become an effective nondestructive testing method for soil-nailing inspection. Previous studies utilized a preinstalled, single-core, electric wire alongside the rebar within the soil nail. Measurements may be affected by possible grout defects and excessively overestimate the rebar length if the wire is coiled around the rebar. An improved TDR waveguide and a corresponding decoupled data reduction method (for both soil-nail length determination and grout condition inspection) are proposed herein. The feasibility and advantages of the new approach were experimentally verified with two types of TDR device. The proposed methodology makes it possible to use a portable, low-cost, and low-speed TDR device as a quick and economical tool for quality control of soil nailing. 出版者： American Society of Civil Engineers 出版日期： 2016-01-01 出處： Journal of geotechnical and geoenvironmental engineering, 2016-01, Vol.142 (1) 資源來源： EBSCOhost Academic Search Premier 版權： 2015 American Society of Civil Engineers 識別號： ISSN: 1090-0241 識別號： EISSN: 1943-5606 識別號： DOI: 10.1061/(ASCE)GT.1943-5606.0001372
