Based on the construction of the testing section for the lining of jiping main canal in shandong province of south - to - north water transfer project, the main causes of the cracking from the mechanized lining concrete slabs are analyzed from the aspects of foundation treatment, bedding layer placement, quality of the raw materials for the concrete, placement of the concrete, cutting of the hardened concrete and the curing of the concrete, and then the relevant prevention and control measures are pertinently put forward
摘要結合山東省南水北調濟平乾渠工程襯砌試驗段施工情況，著重從地基處理、墊層料鋪設、混凝土原材料質量、混凝土澆築、成型混凝土割縫及養護幾個方面分析了機械化襯砌混凝土板裂縫產生的主要原因，並針對性地提出了預防及控制措施。Extruded concrete curb technology was introduced in 20th congress icold held in beijing in year 2000, this method draw more attention for its improving the compaction of transition material, excellent performance of slope protection, and convenient construction. this extruded concrete curb technology was developed in ita dam construction in brazil, the ita method consists of building and extruded concrete curb by using an extruding machine before the construction of a layer of the transition material, then spread and level the transition material in layers inside the curb, and compact the layer by vib ' ratory roller horizontally
巴西工程界在埃塔（ ita ）面板堆石壩建設中，借鑒道路園林工程中道沿機的擠壓滑模原理，創造性使用邊墻施工法，在每填築一層墊層料之前，用擠壓式邊墻機製作出一個半透水混凝土小墻，然後在其內側按設計鋪填壩料，用振動碾平面碾壓，合格后重復以上工序。A certain thickness of sand cushion of a certain size or gradation is paved between the foundation and ground in this new method. when earthquake happens the sand cushion will have plastic shearing strain, reducing the input of high frequency volume, thus consume the earthquake energy form substrate. it is showed in shaking table experiments that there is relevant slippage between foundation and sand cushion, which can prevent the seismic energy from being passed to the above structure and thus reduced the seismic role for the above structure
在建築物的基礎與地基之間鋪設一定厚度、某種單一粒徑或級配砂墊層，在地震作用時砂墊層發生的塑性剪切變形，減少地震波高頻分量的輸入，從而消耗了下層傳來的地震能量；振動臺試驗表明，當振動發生時，基礎與砂墊層之間有明顯的滑移產生，這就對地震能量向上部結構的傳遞起到了隔斷作用，因而對上部結構起到了減震作用。
