深埋（DE）或嵌入式贯穿截面（ETS）技术是利用纤维增强聚合物（FRP）或钢筋提高钢筋混凝土（RC）结构抗剪承载力的一种新的加固方法。随着这项技术的发展，钢筋混凝土连续梁的结构性能与DE法加固需要进行严格的调查，考虑关键的影响参数。在本研究计画中，进行了10个试验3840毫米长的钢筋混凝土连续T梁设计，以失败的剪切。本文的研究重点是将深埋技术扩展到考虑T形截面、GFRP和CFRP筋以外的钢筋、钻孔角度（而非垂直钻孔角度）以及连续性对抗剪加固的影响。因此，本研究的主要目的是扩大我们目前的知识的行为，连续梁加强剪切DE酒吧通过改变上述参数。所需的分析模型，以验证收集到的结果和预测行为的这种加强梁的基础。
The Deep Embedment (DE) or Embedded Through Section (ETS) technique is a new retrofit method to increase the shear capacity of reinforced concrete (RC) structures using fibre-reinforced polymer (FRP) or steel bars. Following the development of this technique, the structural behaviour of RC continuous beams strengthened with the DE method needs to be investigated rigorously by considering key influencing parameters. In this research project, ten tests were performed on 3840 mm long RC continuous T-beams designed to fail in shear. The research presented here is focused on the extension of the Deep Embedment technique to consider T sections, GFRP and steel bars besides CFRP bars, angles of drilling other than vertical, and the effects of continuity on shear strengthening. Therefore, the main objective of this study is to expand our current knowledge on the behaviour of continuous beams strengthened in shear with DE bars by varying the parameters previously mentioned. The basis for an analytical model required to validate results collected and to predict behaviour of such strengthened beams is presented.
