摘要文章針對某輪船舶廢氣鍋爐燒塌的現象，系統分析了廢氣鍋爐燒塌的機理和原因，並根據該輪的實際情況提出了若干預防措施。Through experiment and analyzing the changes of the thickness, rigidity, tensile strength and the opening rate of the conduits caused by the different kinds of coating material, the thickness of the coating and the different braiding structures, we investigate the physical and mechanical, properties of the braided conduits. the results show : the chitosan is easy to form the film structure on the surface of the conduits increasing the conduits ' rigidity clearly ; the rigidity and opening rate of the braided structure with inserted reinforcing yarn are better than the others, this will prevent the conduits collapsing and distorting effectively in the practical uses, so we select conduits of this structure for animal experiment
在導管的物理機械性能研究方面，本課題通過塗層劑的種類（ pgla丙酮溶液和甲殼胺漿液） 、塗層劑的厚度、導管的編織結構三個方面分析它們對導管的厚度、硬挺度、拉伸強力和孔隙率等性能的影響。測試結果顯示：甲殼胺塗層易於在導管表面成膜，對導管的硬挺度有明顯提高，塗層效果較好；加筋結構神經導管在硬挺度和孔隙率方面優于其它導管，能有效防止導管在實際應用中的塌陷變形。Whereafter, based on the analysis on the flood influence for traffic lines, the research is centered on the following parts : firstly, the destroying modes, reasons and mechanism of flooded lines are discussed, and the frameworks and countermeasures of preventing and controlling hazards system are put forward ; secondly, the ways of region forecasting for the landslide are analyzed and the automation of landslide forecast for certain site through visual programming is realized. furthermore, the function of dynamic segmentation in arc view is made use of to realize the forecast result ' s visualization ; thirdly, the reasons and patterns of roadbed subsidence are discussed and the methods of forecasting subsidence based on the gm ( 1, 1 ) model are put forward. then the applications of the arcview software and its extended module on the study of roadbed subsidence are debates upon ; fourthly, an analysis on the sources of flood for traffic lines, which situate in the reservoir coverage area, is given

防塌機理Wld is a high - temperature anti - sloughing agent, which contains si and organic compound ion. by applying it with polymer drilling fluid in the high - temperature deep well and the well section of heaving mud shale, it can improve the stability of drilling fluid dramatically. and at the same time, it can deactivate the drill cuttings and the wall surface active point to greatly improve the property of rejection and anti - sloughing of the drilling fluid through the physical - chemical action occurring between the special group of molecule vs. drill cuttings and the wall surface
Wld高溫防塌劑是一種含有si元素和有機復合離子的抗高溫防塌劑，在高溫深井及易垮塌的泥頁巖井段配合聚合物鉆井液使用，不僅可以顯著改善鉆井液的穩定性，而且可以利用分子中的特種基團與鉆屑和井壁表面發生物理-化學作用，使鉆屑和井壁表面活性點鈍化而顯著提高鉆井液的抑制防塌能力。The collapse mainly occurs in the low - water years or during the beginning of the dry season and rain season in a year. the formation and developing scales of the collapse are affected by many factors, such as karst caves, sola and water, etc. however, the taking of the underground water which causes the hydrodynamic conditions changed and the water level highly descended is a leading factor for the karst collapse. the mechanism of karst collapse is discussed based on long - term monitoring results of groundwater level and geological environment
塌陷的產生與發展規模受溶洞、土層和水等多種因素的綜合影響，但過量開采地下水導致地下水動力條件急劇改變或水位大幅度下降是造成塌陷形成的主導因素;進一步討論了泰安市巖溶塌陷的形成機理，在此基礎之上對泰安市巖溶塌陷的監測預報及對土地資源管理利用的影響進行了研究，並根據當地的防治實踐，提出了巖溶塌陷防治的對策建議。It also used to prevent or solve geologic calamity, such as landslide and rock collapse etc. in addition, it is also used to drill small size water well and high - pressure jet grouting hole
