湖南省交通规划勘察设计院叶世杰同志在湖南省地质学会1979年学术年会上提出了两篇工程地质研究报告。一篇题为“长沙湘江大桥基岩承载力的合理使用问题”。报告认为,按以往的有关规程,基岩承载力采用天然(饱和)极限抗压强度的1/6是不合理的。其理由是,在室内进行的岩石抗压试验是单轴受压(无侧限),而在自然界中,岩石虽被不同程度的节理裂隙切割,但周边却紧密相连,是在有一定侧限的情况下受压,
Comrade Ye Shijie of Hunan Provincial Traffic Planning Survey and Design Institute put forward two engineering geological research reports at the 1979 Annual Conference of Hunan Geological Society. An article entitled “Changsha Xiangjiang River bedrock bearing capacity of the rational use of the problem.” According to the report, according to the relevant rules in the past, it is unreasonable that the bearing capacity of bedrock should be 1/6 of the natural (saturated) ultimate compressive strength. The reason for this is that the rock compression test carried out indoors is uniaxial (unconfined), whereas in nature the rock, although being cut to varying degrees by joint fissures, is closely bound to the periphery, The case of pressure,
