Soil body in-situ testing device, system and method
The invention provides a soil body in-situ testing device, system and method, and relates to the technical field of static sounding devices.The soil body in-situ testing device comprises a soil body expansion module, a shear wave velocity measuring module and a static sounding module which are sequentially connected from top to bottom; the soil body expansion module comprises a supporting rod, an expansion film, an expansion pressure applying structure and at least one group of transverse displacement sensing assemblies, the expansion film sleeves the supporting rod, the transverse displacement sensing assemblies are arranged between the outer wall of the supporting rod and the expansion film, and the expansion pressure applying structure is used for applying pressure to the expansion film to enable the expansion film to generate transverse stress and measure the transverse stress; the transverse displacement sensing assembly is used for monitoring a transverse displacement value generated when the expansion film is subjected to transverse stress. According to the soil in-situ testing device, system and method, static sounding, shear wave velocity data measurement and stress-strain data collection in the soil expansion process can be carried out at the same time, and the static sounding operation efficiency is improved.
本发明提供了一种土体原位测试装置、系统及方法，涉及静力触探装置技术领域，本发明提供的土体原位测试装置包括：由上至下顺次连接的土体扩张模块、剪切波速测量模块和静力触探模块；土体扩张模块包括支撑杆、扩张膜、膨胀施压结构和至少一组横向位移传感组件，扩张膜套设在支撑杆外部，横向位移传感组件设置在支撑杆的外壁与扩张膜之间，膨胀施压结构用于向扩张膜施压使其产生横向应力并测量横向应力，横向位移传感组件用于监测扩张膜受到横向应力产生的横向位移值。本发明的土体原位测试装置、系统及方法可同时进行静力触探、剪切波速数据测量及土体扩张过程中应力‑应变数据的采集，提高静力触探作业效率。
