为了解坝体受力情况和土与混凝土建筑物的作用压力大小,从而判断工程的安全,验证设计,重要而有条件的工程可进行土压力观测。土压力观测通常采用土压力计。土压力计分边界式(亦称接触式)和埋入式(亦称土中)两类。前者用于测量诸如基岩、混凝土结构物表面与土体、地基土等的接触压力,后者用于测量坝体壤土中的内部土压力。
In order to understand the dam body force situation and the pressure of soil and concrete structure, so as to judge the safety of the project, validate the design, important and conditional project can carry out earth pressure observation. Soil pressure observation is usually used earth pressure gauge. Earth pressure points boundary (also known as contact) and buried (also known as soil) two categories. The former is used to measure the contact pressure of the surface such as bedrock and concrete structure with soil, foundation soil, etc. The latter is used to measure the internal earth pressure in the loam of the dam body.
