摘要：本研究通过现场数据调查、结构设计分析、施工质量问题评估及使用环境影响分析,系统研究了襄阳市某商务大楼连廊支撑牛腿开裂的成因。现场检测结果显示,牛腿开裂主要由施工质量问题引发,特别是钢筋定位不准确和混凝土保护层厚度过厚,同时锚固位置有误进一步加剧了裂缝的扩展。在分析事故原因的基础上,综合对比了多种加固方案,最终选择了外包钢加固作为主要解决方案。加固完成后,通过静载试验、超声波检测和应变监测验证了方案的有效性,结果表明加固后的牛腿在承载力和结构稳定性方面显著提升。研究最终提出了针对类似工程的建议,强调了施工质量控制和合理加固方案选择的重要性,以保障建筑的安全与耐久性。This study systematically investigated the causes of corbel cracking in the corridor support of a commercial building in Xiangyang through on-site data collection, structural design analysis, construction quality evaluation, and assessment of environmental impact. The on-site inspection results showed that the cracking was primarily caused by construction quality issues, particularly inaccurate rebar positioning, and excessive concrete cover thickness, while incorrect anchoring further exacerbated the crack propagation. Based on the cause analysis, various reinforcement options were compared, and external steel reinforcement was ultimately selected as the main solution. After the reinforcement was completed, the effectiveness of the solution was verified through static load testing, ultrasonic testing, and strain monitoring. The results indicated significant improvements in the load-bearing capacity and structural stability of the corbels. Finally, the study provides recommendations for similar projects, emphasizing the importance of construction quality control and the selection of appropriate reinforcement solutions to ensure building safety and durability.

摘要：木墩机粉碎系统工作时由于负载变化频繁,常会出现液压马达输出动力不足导致粉碎鼓卡死等现象。设计了以负载敏感变量柱塞泵为核心元件的液压粉碎系统。在深入分析木墩机粉碎系统不同工况基础上,在AMESim平台下建立了基于负载敏感控制的木墩机粉碎系统仿真模型,并对其进行了静动态仿真。仿真结果表明:通过调节负载敏感阀和恒压阀的弹簧刚度可以缩短系统响应时间,实现系统优化;负载敏感粉碎系统输入执行元件的流量只与换向阀阀口的开度有关,与外界的压力(负载)大小无关。负载敏感粉碎系统能够实现木墩机节能降耗,提高整机的工作可靠性。

摘要：针对液压上卡盘在钻探过程中受力变形复杂的问题,为了更好的评估液压上卡盘在工作时内部的变形情况,利用CATIA软件的机械设计模块和有限元分析模块,建立JU-1000型钻机液压上卡盘的三维模型,同时模拟上卡盘内部碟形弹簧组件的结构强度。通过分析碟形弹簧组件的应力与应变,得出JU-1000型钻机碟形弹簧组件的最大应力值控制在材料的许可应力范围内,能够满足钻机对液压上卡盘的工作需求,同时论证了产品设计的合理性。

摘要：红岭中学石厦校区的校园设计是在原有用地范围之内,保留西侧主体教学楼(进行适度的立面改造),对东侧的体育馆和运动场地进行拆除,并在拆除区域建设新的教学与运动空间。新建空间是对现有建筑教学功能的完善和补充,以满足未来共36个全日制班师生的学习和生活要求。设计的初衷旨在探讨一种城市高密度环境下的创新校园空间的可能性。土木石将设计思考聚焦于四个方面:1.如何延续原有校园的空间脉络并最大限度保留原有树木,将新旧建筑作为一个整体考虑?
