摘要在研究船橋墩防護裝置碰撞機理的基礎上，結合實例探討了碰撞問題中的諸多因家（如碰撞位置、防護裝置的結構尺寸以及碰撞速度等的變化）對防護裝置抗撞性能的影響，並據此對橋墩防護裝置提出了改進意見：通過模擬計算，改進防護裝置的板厚以及板上筋的結構尺寸；在防護裝置的內圍壁與橋墩之間放置橡膠吸能元件或在防護裝置的外圍壁安裝橡膠護舷件，以加強防護裝置的吸能作用。At last fire proof of composite slab has been analyzed in this paper
最後本文對組合板的防火設計進行了研究，並對防火保護層厚度進行了計算。It is shown that the bruises of geogrid are decreased if sheep - foot roller is used when lay - down thickness deeper than 30cm. the deformation of geogrid mainly comes of construction. the infiltration of rainwater is disadvantage for the stabilization of geogrid reinforced embankment
研究表明：在填土虛鋪厚度大於30cm的情況下，採用羊腳碾壓路機碾壓能有效減小土工格柵的損傷；實際工程中土工格柵的變形主要來源於施工的影響；雨水的入滲對土工格柵加筋路堤的穩定性極為不利；水泥土是經濟合理的坡面防護措施。First divides the protection structure into the bumper and the rear wall, separately study the impact effect of two plates, the recombination is taking together the overall construction research ; secondly, the protection structure took the overall construction, puts the witness plate behind the rear wall, through surveys the real wall and the witness plate damage traces narrates the projectile destructiveness, the form of witness plate are one layer thick plate or multilayered thin plates
一是把防護結構分成防護屏和艙壁兩層單板分別研究其撞擊效應，再結合在一起作為整體結構研究;二是把防護結構作為整體結構，在艙壁後面放觀測板，通過測量艙壁和觀測板的損傷來描述彈丸破壞程度，觀測板的形式分為一層中厚板和多層薄板。If metal shielding exceeds a centimeter, electromagnetic protection declines drastically, he explains, because impacts by energetic particles can cause strong electromagnetic bremsstrahlung radiation that can result in extensive damage. ( bremsstrahlung is german for the “ braking radiation ” produced when a charged particle decelerates rapidly as a result of collision with another body
他進一步解釋，金屬防護層厚度超過一公分時，電磁防護能力將大幅降低，因為受高能粒子撞擊時，會形成強大的制動輻射，造成更大的損害（制動輻射是由於帶電粒子碰撞其他物體而突然減速所造成） 。Standard test methods for measurement of dry film thickness of protective coating systems by destructive means
