Scale ratio rodless T-shaped penetrometer for measuring undrained shear strength of soft soil
The invention belongs to the technical field of geotechnical engineering soft soil testing, and particularly relates to a scaling rodless T-shaped penetrometer for measuring undrained shear strength of soft soil, the scaling rodless T-shaped penetrometer comprises a T-shaped sounding probe, a geotechnical box and a moving device, an opening groove for containing a soil sample is formed in the geotechnical box, and the moving device is used for adjusting the position of the T-shaped sounding probe in the geotechnical box; the T-shaped sounding device comprises a T-shaped probe, a composite cable, a large-torque stay wire displacement sensor, a gradienter, a pore water pressure gauge, a load sensor A, a load sensor B, a load sensor C, an active winder and a sounding thin plate. A feeler lever is replaced by the composite cable with a relatively small diameter, the influence of the thickness of the feeler lever on measurement is avoided, a high-precision instrument is controlled through a computer, and the measurement accuracy is improved; the pore water pressure of soft soil can be measured while the undrained shear strength is measured.
本发明属于岩土工程软土测试技术领域，具体涉及一种测量软土不排水抗剪强度的缩比无杆式T型触探仪，包括T型触探、土工箱和移动装置，土工箱内部设有用于盛放土样的开口槽，移动装置用于调节T型触探在土工箱中的位置；所述T型触探包括T型探头、复合缆绳、大扭矩拉线位移传感器、水平仪、孔隙水压力计、载荷传感器A、载荷传感器B、载荷传感器C、主动卷线器和触探薄板。本发明使用直径相对较小的复合缆绳代替探杆，避免了探杆粗细对测量的影响，并且通过计算机控制高精密仪器，增加了测量的准确率；在测量不排水抗剪强度的同时还能测量软土的孔隙水压力。
