相对于高应变法和低应变法测试技术而提出中应变法概念。在现有的方法失效或难以开展时中应变法可以作为一种有效的弥补方法,填补高应变法和低应变法之间的空白。本文根据对不同桩型的试验,分析锤重、落距以及锤垫对中应变法的影响,拟定匹配的传感器参数,为后续的关键技术研究奠定基础。 Compared with the high strain method and low strain method, the concept of middle strain method is proposed. When existing methods fail or are difficult to implement, the mid-strain method can be used as an effective remedy to fill in the gap between the high strain method and the low strain method. Based on the test of different pile types, the paper analyzes the influence of hammer weight, distance and hammer pad on the middle strain method, and draws the matched sensor parameters, which lays the foundation for the following key technology research.
