混凝土微裂纹的扩展对于重要混凝土结构或者疲劳荷载下的建筑或桥梁的安全性和耐久性具有较大影响,传统的无损检测方法对微裂纹不敏感,针对此问题,提出一种利用宽频非线性超声调制原理检测混凝土扩展微裂纹的方法。借助扩展有限元仿真法,模拟超声激励含微裂纹混凝土模型产生应力波,对混凝土模型接收点的位移信号进行频谱分析,建立了微裂纹扩展长度与非线性调制法中所定义的损伤指标峰值之间的关系。通过仿真模拟和试验检测,研究了宽频激励下非线性超声检测荷载下扩展微裂纹的可测性,从而实现对混凝土微裂纹扩展趋势的实时动态监测。

Objective: To explore the demographic and disease-related factors associated with acupuncture response in patients with chronic tension-type headache(CTTH). Methods: Using data from the randomized clinical trial(218 cases) consisting of 4 weeks of baseline assessment, 8 weeks of treatment, and 24 weeks of follow-up, participants were regrouped into responders(at least a 50% reduction in monthly headache days at week 16 compared with baseline) and non-responders. Twenty-three demographic and disease-related factors associated with acupuncture response in 183 participants were analyzed by multivariable logistic regression. Results: One hundred and nineteen(65.0%) participants were classified as responders. Four factors were significantly independently associated with acupuncture response, including treatment assignment, headache intensity at baseline, and 2 domains [general health(GH) and social functioning(SF)] from the 36-Item Short Form Health Survey quality of life questionnaire. Treatment assignment was associated with nonresponse: participants receiving true acupuncture were 3-time more likely to achieve a CTTH response than those receiving superficial acupuncture [odds ratio(OR) 0.322, 95% confidence interval(CI) 0.162 to 0.625, P=0.001]. Compared with patients with mild-intensity headache, patients with moderate-intensity headache were twice as likely to respond to acupuncture(OR 2.001, 95% CI 1.020 to 4.011, P=0.046). The likelihood of non-response increased by 4.5% with each unit increase in the GH grade(OR 0.955, 95% CI 0.917 to 0.993, P=0.024) while decreased by 3.8% with each unit increase in the SF grade(OR 1.038, 95% CI 1.009 to 1.069, P=0.011). Conclusions: Greater headache intensity, lower GH score, and higher SF score were associated with better acupuncture responses in CTTH patients. These 3 factors require independent validation as predictors of acupuncture effectiveness in CTTH.
