采用数值模拟方法，对新浇混凝土灌注桩在爆破振动作用下的动态响应进行了分析。考虑到混凝土的徐变、自身体积变形及弹性模量随时间的变化，计算了在温度变化和爆破振动荷载作用下，混凝土及周围岩体的应力分布情况。
採用數值模擬方法，對新澆混凝土灌註樁在爆破振動作用下的動態響應進行瞭分析。攷慮到混凝土的徐變、自身體積變形及彈性模量隨時間的變化，計算瞭在溫度變化和爆破振動荷載作用下，混凝土及週圍巖體的應力分佈情況。

The dynamic response of fresh concrete filling pile under blasting load is studied by numerical simulation in this paper, the factors such as concrete′s creep,self growing volume deformation and change of elastic modulus by time are taken into account and the stress distribution of concrete and rock which surrounds concrete is calculated under the change of temperature and blasting vibration.
