加筋地基的設計內容包括承載力、變形和穩定性計算，故加筋地基的范疇和目的包括增加地基承載力、減小沉降和不均勻沉降，以及提高抗滑穩定性等。 -
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。
