桥梁大吨位桩基新静载试验方法的工程应用

针对桥梁桩基吨位大、试桩场地特殊等特点，采用一种新的静载试桩方法－自平衡试桩法对基进行测试，首先介绍了 平衡试桩法的基本原理，然后介绍了方法在南京新三汊河大桥试桩和润扬长江公路大桥南引桥试桩工程实例中的具体运用，该法成功地解决了采用传统静载方法难以解决的特殊现场试验条件与大吨位试桩问题，在桥梁桩基中具有广泛的应用前景。

Engineering Applications of A New Static Load Testing Method for Piles with Large Bearing Capacity in Bridge

Under the conditions of large bearing capacity and the special testing site of piles in bridge, a new static load testing method,the self balanced testing method, is adopted. The main principle of this method and its applications in Nanjing New Sancha River Bridge and Runyang Yangzi River Highway Bridge are introduced. This method can solve the special testing site conditions and the large bearing capacity of bridge piles, which will find wide application prospect in bridge piles.
