摘　　要：混凝土是一种特殊的建筑材料 ,传统的测量混凝土位移的仪器 ,如机械式测试仪或电子测试仪等都存在某些不足。提出利用机械式机构传递位移和电测仪测试位移相结合的方法测试混凝土位移的原理 ,其核心是解决消除机械式机构中的温度应变的问题。Concrete is a special material of construction. The traditional ways of measuring the concrete's displacement such as the mechanical strain gage, the bonded strain gage and so on all have their disadvantages. In this paper, a principle to measure the concrete's displacement has been presented,the core of which is to offset the displacement of temperature.
