Culvert under high - stack soil is a ubiquitous phenomena in road constructions in mountain, self - compression of high - stack soil can not be ignored, soil pressure at the top of culvert is affected by many factors, including the height of high - stack soil, section size of culvert, width of the bottom of valley, grade of valley, property of filled soil, construction procedure and techniques
高路堤下埋設涵洞是山區公路建設的一種較為普遍的現象，高路堤自身壓縮較大，不可忽視，涵洞頂部土壓力的大小又受很多因素的影響，包括填土高度，涵洞截面尺寸，溝谷底部寬度，溝壁坡角，填築體性狀，施工工序與工藝等。In this thesis, first, reasons and factors for the stability of loose rock dams were summarized according to the field surveys and certain expert ' s experiences. then, researches on block stability problems were reviewed, and according to the relationship between grain size and incipient velocity, it is found that the block weight is in direct proportion to 6 - 9 power of incipient velocity, and 50 % increase of the velocity will result in about 40 times change of the block weight. after that, experiments were conducted in a flume, focusing on the relationship between incipient velocity and some main factors including block weight, water depth over the dam, cross - section size, block material and river bed material
本文首先根據散拋石壩損毀情況的現場調查資料，結合有關專家多年的整治經驗，總結出壩體的損毀原因及影響因素；對現有塊體穩定性的研究成果進行回顧和總結，並針對散拋石壩的直接損毀現象，結合山區河流的水流、地形特點，利用塊體粒徑與起動流速的關系，提出塊體穩定重量與起動流速高次方成正比的概念，流速50的增長可能導致塊體穩定重量接近40倍的變化；通過二維變坡水槽試驗，研究了壩體穩定的主要影響因素，包括塊體重量、壩頂水深、斷面尺寸、塊體材料（塊石和卵石兩種） 、護底等，結果表明對于山區河流，試圖僅僅通過增加壩體單個塊體重量或斷面尺寸來提高壩體穩定性效果甚微；最後，根據西部地區的自然、經濟、交通等條件，提出可以採用柔性混凝土鉸鏈體等一類整體性較好的護面層作為散拋石壩的防沖毀措施，以期取得良好的工程效果。The ingredients limiting power capability and depress combining efficiency in the whole system have been discussed. the infection of the dimension of microstrip line to power capability of devices and the power capability of isolate resistor has been investigated in detail. a high efficiency adaptive power combining technique restraining great degradation in multi - way combining system has been introduced ; 2
文章的主要內容是: 1 .討論了功率合成系統中限制功率容量、降低合成效率的因素;詳細研究了微帶線尺寸對器件功率容量的影響，以及大功率合成系統中隔離電阻功率容量的量值;針對多路合成系統中適度惡化現象合成提出高效率的自適應合成方法。In this more global framework, it would be surprising if the characteristic parameters of the slow instabilities that span a large range of scales ( duration, dimension and amplitude ) did not obey a power - law distribution, just as earthquakes do
在這種更加全球化的框架下，如果跨越很大標度期間、尺寸大小和放大倍數的緩慢的不穩定性因素的特性指標不遵循動力法則分佈，象地震進行的那樣，那才令人奇怪呢。 」分享友人
