盾构区孤石勘察及应对措施探讨

Discussion on Boulder Survey and Countermeasures in Shield Area

孤石发育是花岗岩地区一种常见的不良地质现象,对工程勘察、设计和施工带来较大影响。文中结合厦门轨道交通工程地质勘察及施工实际情况,阐述了孤石对地质勘察、建设施工的影响,结合孤石发育规律,创新性引入了分区勘察技术手段,提高勘察的针对性和实效性,并提出相关施工应对措施,以期为此类地质特征的勘察和施工提供参考。

Boulder development is a common adverse geological phenomenon in granite area, which has a great impact on engineering survey, design and construction. Combined with the actual situation of engineering geological survey and construction of Xiamen rail transit,this paper expounds the impact of boulders on geological survey and construction. Combined with the development law of boulders, this paper innovatively introduces zoning survey technical means to improve the pertinence and effectiveness of survey, and puts forward relevant construction countermeasures, so as to provide reference for the survey and construction of such geological characteristics.
