  1. By direct shear for and normal triaxial shear tests of non - saturated desert sand, the parper studied the effect of water content and dry density on the strength of the non - saturated desert sand, and set up the code of this sand. based on the plane strain test of non - saturated desert sand slope, the paper analysed the destruction way of the excavaion side during the construction by means of adding water, and brough forward a formule that calculates the allowable of excavation and pile hole

    通過非飽和沙漠砂直剪試驗和常規三軸剪切試驗,研究了含水量和干密度對非飽和砂強度的影響,建立了這種砂的強度準則。通過非飽和沙漠砂邊坡室內平面應變試驗,分析了沙漠井場浸法施工中就基坑壁的破壞方式,推導出了基坑和樁孔容許開挖深度的計算公式。
  2. Surface pile density single level pile carpet only

    表面毛絨密度只做單層毛毯
  3. Then the influence to the strength of mix proportion, period and density of pile are analyzed

    分析了配合比、齡期及密實度對樁體強度的影響。
  4. When molding in dry state, it ' s showed that the density is the main influence factor of the strength, which the mechanics property of pile can be increased by improving the density of pile

    樁體採用乾料形態成型,密實度是影響樁體強度的關鍵,改善樁體密實度可以有效提高樁體的力學性質。
  5. Changing the grading of sic particles not only affects the strength and pile density, but also modifies the phase compositions and microstructure of the material. with the reducing of sic particles, the strength of the material increases obviously. the nitrification scheme has the greatest influence on phase compositions and microstructure " of si3n4 ( si2on2 ) - sic, after two continuous nitrification reacting peak and short - time high - temperature treating, the best properties can be obtained ; and the residual strength of the composite is much higher after the thermal shock resistance test, which shows that the material possesses excellent thermal shock resistance

    本論文較全面地探討促進強度和顯微結構良好的si _ 3n _ 4 ( si _ 2on _ 2 )結合相的實驗條件,實驗數據顯示:引入適量的燒結助劑能夠促進si _ 3n _ 4 ( si _ 2on _ 2 )的生成和晶粒的長大,而過量時,其促進作用反而下降;隨著si粉加入量增加,生成的結合相明顯增多,復合材料的性能顯著提高;改變sic顆粒級配不僅影響復合材料的強度與堆積密度,而且對復合材料的物相與顯微結構也有影響,隨著顆粒逐漸細化,材料的強度有較大的提高;對復合材料的強度、物相與顯微結構影響最大的是氮化制度,經過兩個氮化高峰連續的反應和短時間的高溫后處理得到的復合材料性能最好;通過抗熱震性能實驗后復合材料的殘余強度較高,顯示出較好的抗熱震性能。
  6. Through changing and improving the traditionally adopted technology and equipment in compacted lime - soil pile foundation, so as to eliminate weak collapsibility of loess in luoyang and increase the strength of foundation, the authors present formulas to compute the average dry density and void ratio after ground treatment and demonstrate the feasibility of these formulas through practical project cases

    摘要基於洛陽地區次生黃土的弱濕陷性,對傳統的灰土擠密樁施工工藝和設備進行改進,達到消除濕陷性,提高地基承載力的目的,並且推導出地基處理前後干密度和孔隙比隨置換率變化的關系,以工程實例證明該公式的可行性,避免布樁型式的經驗性和處理結果的不確定性。
