摘要:
全长粘结型锚杆广泛应用于多种工程的岩土体加固中，其设计的关键的是采用正确的计算方法和适宜的设计参数，为验证设计参数和施工工艺，施工前应进行锚杆抗拔测试的基本试验。本文针对现行相关规范对锚杆设计及基本试验的相关规定不尽相同这一情况，从全长粘结型锚杆的加固机理出发，对锚杆的设计方法进行了比选，提出了适宜的计算方法。并就基本试验的主要目的进行了分析，提出了最大试验抗拔力预估值、试验锚杆直径和试验锚杆长度应满足的条件。
Abstract:
Full-length bonded anchor bolt is widely used in the rock and soil reinforcement of various projects, its key design is to use the correct calculation method and appropriate design parameters.In order to verify the design parameters and construction technology, the basic test should be carried out before construction. But the relevant regulations on the anchor bolt design and basic test of full-length bonded bolt in current codes are not identical. In view of this situation, based on the reinforcement mechanism of full-length bonded anchor bolt, the design method is compared and selected in this paper, and the suitable calculation method is proposed.The main purpose of the basic test is analyzed too, and the conditions for the pre-estimate of maximum test pulling resistance, the diameter of test bolt and the length of test bolt to be satisfied are put forward.
