利用高温高压射孔实验装置对水泥试样进行了加围压射孔实验,以研究射孔作业对其孔道周围岩石的破坏规律。结果表明:射孔作业对其孔道周围岩石会产生不同程度的损伤破坏,其破坏形式由近孔向外依次为压剪损伤区、拉伸损伤严重区、拉伸损伤衰减区;而随着围压的增加,拉伸损伤严重区范围会减小,裂纹数目减少,损伤程度降低。计算发现孔道周围岩石的渗透率较射孔前有明显增加。本实验结果将为科学分析压裂裂缝起裂规律打下了一定理论基础。  相似文献

为探索桥梁结构损伤与桥面形态的关系,在实验室内利用提取模型桥桥面特征曲率的方法,开展了判定桥梁结构出现损伤位置及程度的试验。首先,采用徕卡Nova Ms50三维激光扫描系统对有机玻璃模型桥面扫描。在多级损伤工况下,将传统位移计测量数据与扫描获取得到桥面几何形态点云数据进行了对比。从理论层面上对基于特征曲率的桥梁结构损伤识别进行了分析,并提取了实测桥面特征截面的挠度曲线。结果可直观看出:曲率曲线在结构损伤处出现突变,且随损伤程度的增加,挠度曲率曲线突变峰值也发生了相应的增大。  相似文献

报告13例严重颅脑损伤后脑积水,12例行侧脑室-腹腔分流术。手术效果良好,讨论和分析了颅脑损伤后脑积水的发生机理并提出CT扫描是诊断和鉴别诊断的重要手段。认为对于严重颅脑损伤患者经手术或药物治疗后病情无明显好转而又排除了颅内复发性、迟发性或遗留性血肿情况下,就应想到有脑积水的可能。应做CT扫描明确诊断。  相似文献

Sport and recreational activity is a vital part of today's society, and athletic training researchers are playing an important role in gaining a better understanding of how to promote safe and healthy participation for athletes of all ages. This article aims to illustrate the importance of research to prevent and effectively treat sport and recreational injuries. Increased physical activity among Americans is helping to combat chronic diseases such as obesity and diabetes, but injuries related to increased activity are on the rise. We must be responsible in our approach to promoting physical activity and participation in sport, while minimizing risk of injury. Athletic training researchers and colleagues from other disciplines within kinesiology, allied health sciences, and medicine must work collaboratively to identify predispositions to athletic injuries and illnesses. They must further conduct prospective studies that will help clinicians better manage these injuries and prevent their recurrence. This article highlights the progress that athletic training researchers have made to bridge the gap between research and clinical practice.  相似文献

Although competitive athletes exceed recommendations for physical activity while they are competing in sport, this does not necessarily translate into regular physical activity after retirement from sport. Research suggested the nature of competitive sport participation may not be conducive to lifelong physical activity. We propose one element of competitive sport participation that may impede physical activity post-retirement is injury. We propose that Vela and Denegar’s model of transient disablement in the physically active with musculoskeletal injuries (DPA) may be appropriate to examine the long-term consequences of sport-related injury—particularly with respect to physical activity disablement. Based on our review of literature, we propose the physical and psychological effects of injuries in sports present unique long-term barriers to physical activity in former competitive athletes. Future research could use the DPA as a foundation for assessing the long-term implications of sport-related injuries—particularly with respect to physical activity.  相似文献

Children in homes with intimate partner violence (IPV) are at increased risk for physical abuse. We determined the frequency and injury patterns in children who underwent child abuse consultation after IPV exposure by retrospectively analyzing the "Examination of Siblings To Recognize Abuse" cohort of children referred for physical abuse. Children were selected who presented after IPV exposure. Among 2890 children evaluated by child abuse pediatricians, 61 (2.1%) patients presented after IPV exposure. Of the 61, 11 (18.0%) were exposed to IPV, but had no direct involvement in the IPV event, 36 (59.0%) sustained inadvertent trauma during IPV, and 14 (23.0%) were directly assaulted during IPV. Thirty-six patients (59.0%) had an injury: 31 (51.0%) had cutaneous injuries and 15 (24.6%) had internal injuries including fracture(s), intracranial or intra-abdominal injury. Of the 15 patients with internal injuries, 14 (93.3%) were less than 12 months old. Among the 36 patients with injuries, 16 (44.4%) had no report of direct injury, a report of a mechanism that did not explain the identified injuries, or a report of trauma without a specific mechanism. Five (13.9%) did not have physical examination findings to suggest the extent of their internal injuries. Injuries are present in a significant proportion of children presenting to Emergency Departments after IPV exposure. History and physical examination alone are insufficient to detect internal injuries especially in infants. These preliminary results support the need for future, prospective studies of occult injury in children exposed to IPV.  相似文献
