1 锚杆的试验为了确定锚杆的极限承载力,验证锚杆设计参数和施工工艺的合理性,检验工程锚杆的工程质量或掌握锚杆在软弱地层中工作的变形特性,对锚杆要进行各种试验,主要有基本试验、蠕变试验和验收试验。 1.1 一般要求对于各种锚杆试验,均必须满足下列基本要求: (1)锚杆试验用加荷装置(千斤顶、油泵)的额定压力必须大于试验压力。 (2)锚杆试验用反力装置在最大试验荷载作用下应保持足够的强度和刚度。 (3)锚杆试验用检测装置(测力计、位移计、计时
1 In order to determine the ultimate bearing capacity of the anchor bolt, and to verify the rationality of the design parameters of the anchor rod and the construction process, the anchor bolt is to be inspected for engineering quality of the anchor bolt or to master the deformation characteristics of the anchor bolt working in the weak formation. Various tests are carried out, mainly basic tests, creep tests and acceptance tests. 1.1 General requirements For various bolt tests, the following basic requirements must be met: (1) The rated pressure of the loading device (jack, oil pump) for the bolt test must be greater than the test pressure. (2) The anchorage test reaction force device shall maintain sufficient strength and rigidity under the maximum test load. (3) Testing device for anchor rod test (Dynamometer, displacement meter, timing
