锅炉除尘器运行状态下的基础改建

锅炉除尘器运行状态下的基础改建周振生太原二吐厂６炉除尘器是水膜式除尘、砖砌筒壁底框架支撑结构，由于运行使用多年，筒壁多处裂缝，砖体风化剥落严重，虽经加固，仍很不安全，根据检修部门选型的意见，拟改为水膜式麻石筒壁除尘器。由于除尘器筒体结构改变，原框架系...

Discussion Based on Formwork Construction of Box Girder Formwork Design Scheme

Formwork construction has been the important and difficult of the construction process, so the design plan is very important. This paper relies on the Shun Ping Yu subordinate Fertgbo bridge rebuilding project, detailing the cast-in-place box beam formwork support system safety special construction plan, focuses on box girder formwork design scheme of foundation design, box girder bracket design and box girder formwork design, to provide a reasonable reference for similar projects.

基于模糊综合评价法的佛山某厂房基础工程稳定性评价

基于钻探法和区域地质资料对佛山市某厂房基础改建工程进行了岩土工程勘察。在详细分析场地地质构造特征和岩溶发育特性的基础上,选取了14个影响场地稳定性的不利因素评价因子,建立AHP-Fuzzy分析模型对勘察钻孔所在场地稳定性进行评价,以各钻孔评价分数为基准,利用等高线地形图法绘制场地的稳定性分区,提出预应力混凝土管桩现场施工建议。与管桩施工的地基承载力检测结果进行对比,结果表明:本方法对场地稳定性评价结果较为准确,验证了评价方法的可靠性,可为类似工程勘察设计施工提供参考。
