By the large quantity of indoor and field soil mechanics test, this paper investigated physics and mechanics property of xigeda stratum and xigeda compounding filling, profoundly and systematically studied on shearing strength, cbr ( including indoor cbr and field cbr ) and intensity feature of xigeda compounding filling. the new achievement and cognition as follows : ( 1 ) cbr value is decided by moisture content and mudstone content of xigeda compounding filling. the filling material can satisfy minimum intensity standard of express highway when mudstone content is less than some fixed value, ( 2 ) this paper established field cbr standard value which can synthetically evaluate the filling material nature and field compaction degree. ( 3 ) the optimal compacting mean of xigeda compounding filling is hard oscillation first and weak oscillation later, not traditional way which is weak oscillation first and hard oscillation later. ( 4 ) this paper put forward the conception of optimum moisture content in construction different from optimum moisture content of indoor impaction
本文以昔格達填料強度特徵為研究對象，通過大量的室內及現場試驗，從昔格達地層巖組的物理力學性質、昔格達填料的物理性質入手，對昔格達填料的抗剪強度、室內承載比及現場承載比特徵進行了較系統地研究，獲得了如下認識及進展：昔格達混合填料承載比值受填料含水量及其中泥巖含量的影響，當泥巖含量小於一定值時，昔格達混合填料具有較高的承載比值，能夠滿足高速公路對填料的最低強度要求；建立了綜合評判昔格達填料性能及現場壓實效果的現場承載比（ cbr ）標準；對于昔格達填料而言，最佳的碾壓方式為先強振后弱振而不是傳統的先弱振后強振；提出了與室內擊實最優含水量相區別的施工最佳含水量的概念。 -
On may 3, invited by the institutes deputy directors liu xiaobing and hu naizhe, dr. mclaughlin visited the experimental park in harbin and the black soil ecological experiment station in hailun. with deputy director liu xiaobing and the research fellow zhang xingyi, he had an in - depth discussion of some issues of common interest to both sides, like the deterioration and management of black soil, conservation farming, compacting of soil
5月3日， neil博士應劉曉冰副所長和胡乃哲副所長的邀請，訪問了我所哈爾濱園區以及海倫黑土生態實驗站，與劉副所長張興義研究員等圍繞黑土退化與管理保護性耕作土壤壓實等雙方感興趣的問題進行了深入的交流。 -
The experiential formula between kc and base resistance q from cpt and, the relationship between ke and c # ( strength of concrete ) are also created by fitting 94 pressed pile testing date. based on analyzing the compacting effects caused by driving pile in loess and it ' s influence on bearing capacity and settlement, another two disturbance parameters, c and e, are proposed for multiplying respectively the parameters of soil cohesive c and deformation modulus es to reflect this effect. by fitting 51 driven pile testing date, we created an experiential formula between the e and r ( the modulus ratio between pile and surrounding soil ), also an experiential formula between the c and base friction resistance fs / pa from cpt of pile surrounding soil
在本文中分析了靜壓樁的沉樁擠土效應對其承載力與沉降特性的影響，在計算模型中引入了樁周土粘聚力c的修正系數k _ c和樁周土變形模量e _ s的修正系數k _ e來體現這種影響，通過對94根靜壓樁試樁資料進行擬合，建立了k _ c與樁端土靜力觸探的端阻q _ c之間經驗公式以及k _ e與c # （混凝土標號）之間的對應關系。 -
Firstly, gravel piles in soil were laid for compacting and consolidating soil, then gravel composite foundation was treated with dynamic compaction in order to form three - level soil that is gravel composite soil and high replacement ratio composite foundation and dense composite foundation
該法先在填土層中設置好碎石樁體，利用擠密和排水固結的作用使其得到初步加固，然後對荷載影響深度范圍內的復合土體進行低能強夯處理，迫使樁體碎石沿徑向擴散，形成上部為密實的碎石二合土層、中部為擴徑后高置換率復合地基、下部為整體夯密復合地基的三層結構。 -
In this paper, depending on the enormous 356 pile testing date detailed with soil and pile parameters and p ~ s curves, covering xi ' an and adjacent areas, we analyzed the load transmission mechanism of pile in loess foundation, and proposed a kind of hyperbolic load transmission function between pile and it ' s neighboring soil. meanwhile, we created a mathematical model to predict p ~ s curve and bearing capacity of single pile. by analyzing the compacting effect caused by pile - sinking of pressed pile in loess and it ' s influence on bearing capacity and settlement, two parameters, kc and ke are introduced to modify the soil cohesive c and deformation modulus es
本文利用現己收集到的西安及其周邊地區356根打入樁、靜壓樁、灌注樁的現場試樁資料（其中打入樁67根，靜壓樁121根，鉆孔灌注樁168根，並有詳細的地層勘探資料，樁深資料，荷載沉降?曲線）對西安黃土地基中的打入樁、靜壓樁、灌注樁的荷載傳遞機理進行了分析研究，認為用雙曲線型的荷載傳遞函數模擬樁土之間的荷載傳遞函數是合適的，並用荷載傳遞分析的方法建立了計算p s曲線的數學模型及極限承載力的確定方法。 -

The integrate expressions of large strain are deduced by means of spm. and the difference of the soil compacting effects in the condition of large strain and small strain is analyzed. secondly, according to the analytical expressions of single jacked pile, the displacement fields of subsequent jacked pile due to the presence of adjacent pile are obtained
2 、在得到靜壓單樁擠土產生位移場的基礎上，運用拉格朗日插值法得到了已存在樁的情況下壓樁產生的土體位移場，並推導了二樁，排樁及靜壓群樁施工產生的迎樁面及背樁面位移場的解析式。
