Application of Lateral Pressure Test in Deep Soil Exploration
The applicability of the lateral pressure test in deep soil exploration was verified through on-site lateral pressure tests and comparative analysis with the results of standard penetration tests.The on-site test results show that the initial pressure of the lateral pressure test is basically linearly related to the depth of the formation.For the same type of soil,both the plastic pressure and ultimate pressure in the lateral pressure test tend to gradually increase with the depth of the soil layer.The deformation parameters of soil are mainly affected by soil properties.For the same type of soil,its lateral modulus is smaller than the deformation modulus but larger than the lateral shear modulus.As an in-situ testing method,the lateral pressure test can obtain both the strength parameters and deformation parameters of the soil layer,making it a good method for deep soil exploration.
