this paper, regarding the asphalt pavement in the zhoukou region as the study object, according to the prevalent norms ( specifications for design of highway asphalt pavement ), with the beginning of the pavement performance and the transportation investigation, totally and systematically analyzes the traffic parameters and the destroying reason of pavement at the early stage in the point of fatigue property and limit strength, gives the concepts and methods of the growth rate of equivalent axle load action time, seasonal modification factor and overload factor, proposes the method of axle load conversion on the condition of heavy loading . on this basis, it proposes the design method adapting to asphalt pavement construction, explains the steps of thickness computation of construction with the combination of engineering example, finally verifies thedesign method in the paper by test road . theory and practice both prove that the reasonability of pavement structure style and the reliability of design method in the paper can adapt to the present heavy loading and overloading traffic conditions, have highly theoretical and practical value 本文以周口地區(qū)瀝青路面為研究對象,以現行《公路瀝青路面設計規(guī)范》為依據,從路面使用性能和交通特征的調查入手,從疲勞特性和極限強度出發(fā)分析了路面早期破損的原因,全面系統(tǒng)地進行了交通參數的分析,提出了當量軸次增長率、季節(jié)修正系數和超載系數的概念和方法,并提出了重載交通的軸載換算方法。在此基礎上,針對超載、重載交通從結構組合設計、結構厚度計算(包括疲勞強度標準和極限強度標準)等方面提出了適宜的瀝青路面結構設計方法,并結合工程實測,說明了結構層厚度計算的具體步驟,最后通過試驗路驗證本文提出的設計方法。理論與實踐均表明,本文提出的路面結構型式合理、設計方法可靠,能適應目前重載、超載交通的狀況,具有較高理論與實用價值。
during the street fight we used the dwelling-size plan employed by the property developer as advertisements . they turned out to be seriously distorted for we found the inner place of all units are extremely insufficient . we could not get any big guns into the rooms originally proposed as our strongholds . besides, the buildings could not be relied on as bunkers for their very limited strength 打巷戰(zhàn)時,我們使用的房地產商作為廣告宣傳的戶型圖嚴重失真,所有戶型內部空間狹小到了令人恐懼的地步,重型武器均無法運入戰(zhàn)前選為要塞的房間;且房屋強度嚴重不足,無法作為戰(zhàn)斗用掩體。
in the light of its special property being not easy to gain strength, through mechanics researches on different methods to stabilize this kind of low _ liquid _ limit silty soil as subbase material, evaluated both technically and economically, we have got a cement lime stabilization plan to meet the index requirements for non _ side _ limit strength of compression of subbase of class2 road stipulated in the specification; by means of improving the workmanship, thickening the loose layer of soil, adding soil on covering weave fabric before compaction, such problems can be solved as very poor compaction, loose surface during compaction, roughness and unevenness, coats of layer and shear damages 本文針對黃河沖積而成的低液限粉土其粘粒含量極低、土的不均勻系數很小、膠體活性差的工程特性,通過采用不同方法穩(wěn)定該類土作底基層材料的力學性能研究,從技術、經濟角度綜合評價,得到滿足規(guī)范抗壓強度指標要求的水泥石灰穩(wěn)定方案。通過對原材料、試驗配合比設計、施工、等方面進行優(yōu)化,從而顯著減輕了基層的早期及長期縮裂程度,從而提高了路面的耐久性。
the basic principle of operation of coordinate legal control that it can ensure the validity of actual macro control is those : through the function of its communication and coordination, and under the coordination, it leads the limiting strength to the field of macro-control . this prevents the government to misuse its power, and it also improves the regulating ability of the government . moreover, the basic essence of macro-controlled substantive law can be found and the defect of substantive law to macro-control actions also can be supplemented 其對宏觀調控合法性保障的基本原理就在于,通過其溝通協(xié)調等功能,引導制約力量在協(xié)調精神的指引下進入宏觀調控領域,既限制政府宏觀調控濫權行為的發(fā)生,又促進政府自身調控能力的改善,并且在宏觀調控的過程中,不斷發(fā)現宏觀調控實體法的基本精神,彌補實體法律對宏觀調控行為控制力的不足。
