本文介绍一种多功能触探样机及其独特的测试方法。发展这项崭新的岩土工程技艺的目的在于改变和扩容现有的静力触探功能,使之成为静动双态和物理力学参数兼测的原位测试工具。在新的探测指标中,有土的冲剪强度Sp,经室内模型试验证明,土的冲剪破损机理与三轴试验压剪破损完全一致,从而可以测求土的抗剪强度τ(c,φ)指标。为求得土的动力学参数,样机中装设有三维检波器,在正反双向贯入过程中,可根据需要反复验证某一土层的纵横波速,从而求得土动力学指标。所有各项静动力学参数测试,均可通过一次向下贯入和向上提升多功能触探头来完成。 This article describes a multi-purpose probing prototype and its unique test method. The development of this new geotechnical engineering aims to change and expand the existing static cone penetration function, making it an in situ testing tool for static and dynamic dual-state and physical and mechanical parameters. In the new detection index, there is soil punching strength Sp, indoor model tests show that the soil punching shear damage mechanism is exactly the same with the triaxial test compression shear damage, which can measure the soil shear strength τ (c, φ) indicator. In order to obtain the dynamic parameters of soil, a 3D detector is installed in the prototype. During the process of forward and reverse bi-directional penetration, the vertical and horizontal wave velocities of a soil layer can be repeatedly verified as needed to obtain soil dynamic indexes. All of the static and dynamic parameters of the test, can be a penetration down and up to enhance multi-touch probe to complete.
