中文拼音 [jiǎoyāsùjī]
角壓塑機
英文
angle press-
This is a thread producing machine which uses its three thread rolling dies, mounted in the same seperation angle of 120 ', to realize roll forming of the workpiece, for metal has the performence of plastic deformation under the pressure operation
該機床是利用金屬在壓力之下產生塑性變形的特點，用三個互成120度夾角的滾模，對工件進行滾壓成型的螺紋加工設備Finally, the reason that the performances of new construction putty were improved was analyzed from the point of micro by sem, edxa and mip. the result and phenomena were explained in the course of experiment, the mechanism about shrinkage at early age and anti - cracking of polypropylene fiber were discussed elementary
最後，本文藉助掃描電鏡（ sem ）和能譜分析（ edxa ）及汞壓力測孔法（ mip ）等現代測試分析手段，從細觀的角度分析了新型外墻膩子粉性能改善的原因，並初步探討了聚丙烯纖維膩子的塑性收縮及阻裂增韌機理。Based on the former research, several works in this paper is listed as follow, which is studied by experiment research, theoretical analysis and numerical calculate : firstly, based on local observation and laboratory experiment result, consolidation mechanism of vacuum - surcharge preloading is analyzed form typical mechanics and microstructure seepage factor. a great deal of observed dada is employed to analyze the deformation characteristics of soil after being treated and variation law of pore water pressure
本文在前人工作的基礎上，通過試驗研究、理論分析、數值計算等手段主要進行了以下幾方面地工作： （ ）分析了大量現場觀測成果及室內外試驗資料，從經典力學和微觀滲流兩個角度解釋了塑料板排水真空-堆載聯合預壓法加固軟基機理，總結了該法加固的土體變形特點、孔隙水壓力變化規律。Abstract : based on soil plasticity and limit analysis theory, the second failure surface of backfill behind retaining wall with gentle back surface are studied from two view points of maximum active soil pressure and minimum resistive overturning safety factor, and it is further considered that the minimum resistive overturning safety factor is the best approach to studying the failure mechanism of backfill under complex back surface conditions of retaining structures
文摘:基於土的塑性極限分析理論，從擋土墻最小抗傾覆安全系數和擋土墻背上的最大主動土壓力兩個角度，分別研究了坦墻後土體中第二破裂面的位置，認為在復雜的擋土結構墻背條件下，用最小抗傾覆安全系數來研究擋土墻後土體的破壞機制較為合理。分享友人
