Embodiment Construction
[0026] The present invention is described in further detail below in conjunction with accompanying drawing:
[0027] refer to figure 1 , the triaxial testing method that is used for measuring the shear strength index of rammed earth wall of the present invention comprises the following steps:
[0028] 1) Prepare soil samples in combination with the manufacturing process of rammed earth walls in engineering practice, and the materials and proportions required for preparing soil samples. Among them, the moisture content requirements of the soil samples obtained after stirring are consistent with the manufacturing process of rammed earth walls in engineering practice ;
[0029] 2) According to the construction technology requirements of the rammed earth wall, ramming is carried out in the sample cylinder to obtain a cylindrical sample;
[0030] Specifically, clean and air-dry the sample cylinder, and then coat a layer of vaseline on the inner side, and then perform compaction i...
