摘　　要：从理论上给出了当基桩存在浅部严重缺陷时 ,在受到瞬态激振力的情形下 ,桩体上段振动的数学模型 ,并结合工程实践 。A mathematical model of the vibration at the upper segment of a pile when there exist severe defects is put forward based on theoretical analysis, and the curve characteristics of its low strain test is described according to engineering practice under condition of transient shock.
