| 摘 要： | 将光导纤维、形状记忆合金、压电材料、电阻应变丝、疲劳寿命丝、碳纤维、半导体材料等进行定性比较，结果表明使用这些智能材料对土木工程结构进行短期短期检测是可行的。光纤是用于长期监测的最理想材料；疲劳寿命丝是寿命预测、评估用最理想的材料；若将几种材料在制作传感器时相融合会得到更好的效果；右想在结构的监测过程中还需对其施加作用力，形状记忆合金与压电材料则最为理想。

| Abstract: | Some smart sensing materials, which are used commonly, such as optic fiber, shape-memory alloy, piezoelectric material, resistant strain wire, fatigue life wire, carbon fiber, semiconductor material, etc., have been compared. The results shows that all these smart materials are suitable for short-term testing.Optical fiber is best for long-term monitoring.Fatigue life line is best for life prediction and evaluation.Several materials could be put together to get better effects.Shape alloy and piezoelectric materials can be used as sensor and actor. |
