摘要
码头施工中,由于受地质因素影响,岩层上覆盖层较薄,在其结构选型上,多采用嵌岩灌注桩。嵌岩灌注桩岩层的确定,是设计、施工、监理等各方均非常关注的核心问题。嵌岩灌注桩施工中如何确定中等风化岩层和微风化岩层的高程,如何准确地判定其岩性,成为当前迫切的任务。阐述嵌岩灌注桩施工中,经常遇到的岩层确定问题,提出了对策并成功应用于实际工程。
In wharf construction,since the covering layer of strata is very thin due to the affection from its surrounding geologic condition,the rock-socketed filling pile has been widely applied.The judgement of the terrane＇s quality of rock-socketed filling pile is the key in the design,construction and supervision.This paper expounds the judgement of the terrane＇s quality during constrution of rock-socketed filling piles,and proposes countermeasures which have been applied to the real project.
