摘　　要：介绍了一种既观测桩顶沉降又观测桩端沉降的静载荷试验方法。区别于常规的静载荷试验,该静载荷试验能够提供多方面的参数,可以对桩身弹塑性压缩量、侧阻和端阻的发挥程度、桩端持力层性状有一个比较全面的了解,值得推广。A multiparameters test method of static load is presented. Compared with routine test,the bottom and top settlements can be observed by this method and multiparameters are acquired. Based on these parameters,a general analysis can be made on the elasto-plastic compression of the pile,the side and bottom bearing capacity as well as the properties of the soil under pile.
