Pile-soil interface multi-physical field monitoring method for composite foundation precast pile in permafrost region
The invention discloses a pile-soil interface multi-physical field monitoring method for a composite foundation precast pile in a permafrost region, and relates to the pile-soil interface multi-physical field monitoring method for the composite foundation precast pile in the permafrost region. The invention aims to solve the technical problem that physical and mechanical characteristics such as stress and strain of a pile-soil interface of the existing precast pile composite foundation cannot be monitored on site. The method comprises the following steps: S1, drawing a line on a pile body; s2, grooving the precast pile; s3, pile head hole guiding; s4, marking a sensor; s5, installing a sensor; s6, fixing the sensor; s7, fixing a sensor joint; s8, protecting the interior of the pile top; s9, pile top cover plate protection; and S10, a prefabricated pile sensor lead is obtained. The effectiveness of the sensor can be effectively protected, the problem that the sensor is damaged by friction force between the pile and soil in the pile pressing process when the sensor is attached to the surface of the precast pile is solved, and the reliability of on-site monitoring of the test between the precast pile and the soil of the composite foundation can be achieved.
一种多年冻土地区复合地基预制桩的桩‑土界面多物理场监测方法，涉及一种多年冻土地区复合地基预制桩的桩‑土界面多物理场监测方法。本发明是要解决目前预制桩复合地基的桩‑土界面应力应变等物理力学特性无法现场监测的技术问题。本发明是按以下步骤进行的：S1、桩身画线；S2、预制桩切槽；S3、桩头引孔；S4、标记传感器；S5、安装传感器；S6、固定传感器；S7、固定传感器接头；S8、桩顶内部保护；S9、桩顶盖板保护；S10、预制桩传感器引线。本发明能有效保护传感器的有效性，避免了传感器贴于预制桩表面在压桩过程中被桩与土之间的摩擦力破坏的问题，还能实现现场监测复合地基预制桩桩‑土之间测试的可靠性。
