三、常用动测方法简介(一)概述动力打桩公式是最早采用的动测方法,曾经一度成为除静载试验外唯一能用来判断桩的承载力的现场试验方法,至今已有100多年的历史了。该法实际上是通过控制打桩至规定的贯入度,以此作为施工时检验每根桩的承载力的标准。经过不断改进,动力打桩公式仍然是打桩监测的重要依据。但由于该法的准确性较差,在确定桩基设计参数时还应该发
III. Introduction to commonly used motion measurement methods (1) Overview The dynamic piling equation is the earliest used motion measurement method and was once the only field test method that can be used to determine the bearing capacity of piles except the static load test. It has been more than 100 years. History. This method is actually used as a standard to check the bearing capacity of each pile during construction by controlling the pile to the specified penetration. After continuous improvement, the dynamic piling formula is still an important basis for piling monitoring. However, due to the poor accuracy of the method, it should also be issued when determining the design parameters of the pile foundation.
