浅谈高层建筑桩基勘察的岩土工程评价方法

Evaluating Method of Rock-soil Engineering for the Stake-base Survey in High Buildings

主要探讨在高层建筑桩基勘察工作中，当设计要求不很明确条件下，如何在一次性勘察工作中满足桩基详勘的评价和估算要求．文中对桩基方案的布桩、选桩、荷载估算、单桩尺寸确定，单桩承载力估算等评价方法作了介绍．指出了目前勘察评价的某些问题，并同时介绍了新编“建筑桩基技术规范”中有关桩和桩承载力估算等方面的新概念和方法．

In stake-base survey of high buildings,how to satisfy its evaluation and esti- mation for the stake in primary prospecting is discussed.The evalualing methods of laying and se- lecting stakes,the estimation of load and bearing capacities and the definition of measurement for single stake,etc.in the stake-base scheme are presented.Some existing problems,new concepts and methods concerned are pointed out.
