  1. The collapsible loess is often met during the construction of the high - grade highway in the loess area, and the main failure is the uneven subsidence of the roadbed and the culvert, which affects the safe usage of the roadbed and the culvert, etc. directed against this, based on the chankou - lanzhou freeway construction, the paper analyzes the application of the composite ground formed by lime - soil pile under the bridge and designs the project, discusses the rules of the contact pressure, the stress ratio of the pile and the soil, compares the p - s curves of one pile, the composite ground formed by one pile and the composite ground formed by two piles based on the in - situ plate loading test, evaluates the bearing capacity of the composite ground of the project

    黃土地區的高等級公路建設中經常遇到濕陷性黃土問題，其病害類型主要是地基土受水浸濕后引起路基、橋臺、涵洞等的不均勻沉降，直接影響路基、構造物等的正常使用。針對此問題，本文依託甘肅讒口至蘭州柳溝河高速公路建設工程，對橋基灰土樁復合地基應用的可行性進行了深入分析，根據具體工程進行了合理的設計與計算，並配合現場靜載荷試驗及壓力盒實測數據，探討了基底應力分佈規律，樁土應力比，變形模量的變化關系，對比分析了單樁、單樁復合和雙樁復合的p ? s關系，對橋基灰土樁復合地基承載力進行了整體評價。
  2. The interface behavior between essence and ethylene - vinyl acetate copolymer pallets was studied so that necessary data were obtained to guide the preparation of fragrant masterbatch. the adsorption type and wettability between essence and the copolymer pallets were analysed by measurements of fourier transform infrared spectrum, surface tension, contact angle and specific surface area. the technical factors affecting absorptivity such as the charge ratio, temperature, pressure and stirring speed were studied by series of adsorption experiments. the results showed that the adsorption of essence on the surface of ethylene - vinyl acetate copolymer pallets is physical in nature. essence couldn ' t moisten the surface of ethylene - vinyl acetate copolymer pallets absolutely, but it could be soaked into the surface of the pallets partly. adsorptivity could be increased by enhancing the temperature, pressure and stirring speed, but the extension of adsorption time had little influence on adsorptivity

    研究了香精與乙烯/醋酸乙烯共聚物粒子之間的界面行為，以便為香型母粒的制備提供必要的理論依據.利用傅立葉變換紅外光譜、表面張力、接觸角及比表面面積等測定手段，分析了香精與載體之間的吸附類型和潤濕作用.並通過一系列吸附實驗，討論了配料比、溫度、壓力、攪拌等工藝條件對吸附量的影響.結果表明，香精在乙烯/醋酸乙烯共聚物粒子表面的吸附為物理吸附；香精無法完全潤濕載體粒子表面，但可以對其形成部分浸潤；提高溫度、壓力、攪拌速度可以增加吸附量，而延長吸附時間對增加吸附量貢獻不大
