摘要
针对岩溶地区的工程地质特性,在比较传统加载试验装置的适应性基础上,提出采用锚杆横梁反力装置做桩基静载试验的方法。根据工程实践经验同时结合FLAC3D软件的数值模拟分析,对锚杆横梁反力装置2个关键参数进行了研究,并给出了工程实际应用的推荐值。最后,通过一个工程应用实例,说明了锚杆横梁反力装置在岩溶地区的科学性、可行性。
In this paper videotaping the property of engineering geology in karst area, a bolt counterforce device is proposed for the pile static test based on the comparative studying the accommodation of the different traditional loading test devices. According to the experience of enginerring practice and based on the numeric silmulation and analysis using FLAC3D software ,the text studies two critical parameters of the bolt counterforce device , furthermore presents their recommended values in enginerring practice. At last, the text illuminates the scientificy and flexibility of the bolt counterforce device in karst area by analsysing a engineering example.
