Ancient painted pottery namely chromatic crockery, the department uses hematite pink and oxidation manganese to make dye, use the tool of similar brush, in contented base apparently coloured drawing or pattern all sorts of design, the classics that enter pit 1050 of 900 after baked wheaten cake, on the impression with red orange, present a black, red, design that waits for color in vain
彩陶即彩色陶器，系利用赤鐵礦粉和氧化錳作顏料，使用類似毛筆的工具，在陶坯表面上彩繪各種圖案，入窯經900 1050火燒后，在橙紅的底色上，呈現出黑、紅、白等顏色的圖案。 -
Foundation structure design in soft soils is a very difficult engineering problem. the elastic foundation beam method has some merits such as easy calculation pattern and definite model and m - method is fit to practical situation, so it is used comprehensively and welcome by constructors, thus m - method is recommended by many codes. but it is difficult to select a m - value to some soils, and the codes provides a scope of m - values, and they are different in varied regions and soil conditions, thus it is optional to choose m - value of a soil layer for engineering designers. so it is necessary to calculate m - values by back - analysis method using measured datu of deep foundation pit
軟土地區的深基坑支護結構設計是一個十分復雜的工程問題，由於彈性地基梁法具有計算模式明確、計算過程簡單的優點，尤其是m法較符合軟土基坑工程的實際情況，因而受到廣大工程設計人員的歡迎，大多規范也推薦此法。但是m法計算參數的選取是工程界的一大難題，一般規范都給出了m值的大致范圍，而且每個地區的地質條件千差萬別，因而m的取值具有很大的隨意性，有必要根據一個地區的工程實測資料對m值進行反演分析，以便為地層相近或附近地區的基坑工程設計提供參考和依據。 -
In this paper, scale models are used to study local scour around bridge piers and abutments, and the scour pit pattern and maximum scour depth, which may serve as a reference for engineering design, are given
採用系列模型試驗方法，對具體工程大型橋墩在水流和波流共同作用下的局部沖刷分別進行研究，提出了沖刷坑形態和最大沖刷深度，供工程設計參考。 -
The paper presents a detailed numerical analysis to elucidate the failure pattern of the pit wall, the mechanism of the soil - nailed supporting system and its spatial behavior. firstly, a typical two - layer sand - cobble deposit was chosen for a detailed 2d - fem study. it was shown that due to the distinct behaviors of the upper soft sand layer against the much stiffer lower cobble layer, a bi - linear plane failure was recommended to be used in the limit equilibrium analysis
