第一组第一组的讨论是围绕四个问题来进行的;一、变形模量的测试技术;二、土压力测试技术;三、岩土流变及长期强度的测试技术;四、土体深层水平位移的量测技术——侧斜仪。一、变形模量的测试技术荷载试验是当前确定地基变形模量比较可靠的测试技术之一,试验结果可以反映荷载板底部相当1.5到2倍宽度的深度范围内地基上的力学性质。过去习惯采用的用铁块在承载台上加荷的方法,设备笨重,耗费劳动力,而且试验费用也很贵,已经不适宜当前生产建设需要。1957年以后我国一些单位相继试制成
The discussion of the first group and the first group is based on four questions: First, the test technology of deformation modulus; Second, the earth pressure test technology; Third, the geotechnical rheology and long-term strength test technology; Fourth, the soil Deep horizontal displacement measurement technology - side slope instrument. 1. Deformation Modulus Testing Technology Load testing is one of the most reliable testing techniques for determining the deformation modulus of foundations. The test results can reflect the mechanical properties of the foundation in the depth range of 1.5 to 2 times the width of the bottom of the loading plate. In the past, the method used to load iron blocks on a loading platform was heavy, labor-intensive, and the test cost was also very expensive. It was no longer suitable for current production and construction needs. After 1957, some units in our country have successively made trials
