摘要
同时考虑侧向和竖向加密作用,本文提出估算砂基上抗液化振动挤密桩间距的新方法。通过相对密度D_r和归一化标贯击数(N_1)_(60)的关系,本方法把挤密桩间距的计算与我国抗震规范中液化判别方法联系起来,便于在工程中应用。
A new method to estimate the spacing of vibrocompaetion piles on potentially liquefiable sand foundations by taking account of both lateral and vertical compaction effects is presented herein. This method correlates the calculation of spacing between compaction piles with the method to distinguish liquefaction as stated in Aseismic Code of China through the relationship between relative density D_r and normalized SPT blowcount, (N_1)_(60)′ to facilitate its use in engineering praclice.
