本文简要介绍了旁压仪的结构和构造,在勘探过程中周围地基土的受力特点及其应力——变形关系,并且指出了勘探的两个主要地基参数变形模量Em和极限压力P_1的计算公式。本文第二部分着重分析了如何利用前述两参数来确定非嵌固端摩擦桩任一截面处的摩擦力——位移、横向压力——位移以及桩底竖向反力、横向反力和反力矩与它们相应的位移之间的关系,并且提出了它们各自的模式图。
This paper briefly introduces the structure and structure of the pressure gauge, the stress characteristics of the surrounding soil and the stress-strain relationship during exploration, and points out the deformation modulus Em and the ultimate pressure P_1 of the two main foundations for exploration Calculation formula. The second part of this paper focuses on how to use the above two parameters to determine the friction-displacement, lateral pressure-displacement and the vertical reaction force, the lateral reaction force and the reaction torque at any section of the non-embedded end friction piles With their corresponding displacements, and propose their respective pattern diagrams.
