一、前言静力触探双桥探头已经得到了广泛的应用,但目前各单位所采用的探头规格不尽一致,因而影响了测试成果的对比和交流。为此,我们在有关单位的大力支持和协助下,试图用各种不同的几何外形和有效尺寸的探头,通过对比试验对此问题进行探索,以便提出一个比较合理而能广泛使用的双桥探头的统一规格。试验所选用的双桥探头,考虑了我国《工业与民用建筑工程地质勘察规范》(TJ21-77)中规定的探头有效尺寸和 I. Introduction The static probe has been widely used in double-bridge probes. However, the specifications of probes adopted by various units are not consistent, which affects the comparison and exchange of test results. For this reason, with the strong support and assistance of the relevant units, we tried to explore this issue through comparative tests using various geometric shapes and effective size probes in order to propose a relatively reasonable and widely used dual bridge probe. The uniform specifications. The double bridge probe selected for the experiment was taken into account, and the effective size of the probe as specified in the “Terrestrial Geological Survey Specification for Industrial and Civil Buildings” (TJ21-77) was taken into account.
