预应力锚固工程中测试技术的现状与发展趋势

Present Situation and Development Trend of the Measuring and Testing Techniques in Pre-stress Anchoring Engineering

摘要:

预应力锚杆（索）由于具有主动加固、深层加固、布置灵活、施工快速、对岩(土)体扰动小、经济性好等显著特点，因此在桥梁、边坡、基坑、隧道、大坝加固、结构抗浮和抗倾、地质灾害治理等工程中得到了广泛的应用。总结了预应力锚固工程中常用测试方法与仪器的发展现状和存在的问题，指出了预应力锚固工程测试技术的研究与发展方向。

Abstract:

Pre-stress anchor rod (rope) has the outstanding features with driving reinforcement, in-depth reinforcement, the flexibility in arrangement, short construction period, less disturbance to the rock (soil) body, good economical efficiency and so on, therefore it is widely applied in the engineering of such as bridge, side slope, foundation pit, tunnel, dam reinforcement, anti-floating and anti-leaning structures, geological disaster control and so on. This article summarized the testing method in common use and the present development of the apparatus and existent problems, pointed out the research and development trend of the measuring and testing techniques in pre-stress anchoring engineering.
