广东西部某公路高填方段裂缝补救措施分析

针对广东西部复杂的地质条件,对该区域某高速公路高填方段裂缝进行了分析。通过现场裂缝调研、地质勘察以及初步监测等手段,根据不同的沉降机理(填筑土的自密沉降与地基土的固结沉降)建立了2种不同类型的工后裂缝辨识方法,提出了相关裂缝的不同补救措施,同时对2种沉降中注浆方法的可行性与优缺点进行了对比分析,最后结合相关的后期现场监测数据进行分析论证,结果表明,根据裂缝类型的不同采取相应的针对性补救措施具有一定的可靠性、经济性。

Analysis of Pavement Cracks on High Road Embankment in Western Guangdong and Remedial Measures

The paper proposed two different methods to identify the post construction cracks under complex geolog -ical conditions in western Guangdong .These two methods were developed according to geological survey and field monito -ring as well as the different settlement mechanism （the self tightness settlement of filled soils and the consolidation settle-ment of foundation soil） .Crack grouting methods were proposed to repair the different types of cracks .The paper also analyzed the feasibility of the two settlement methods and compared the advantages and disadvantages of the two settle-ment methods .The remedial measures for different types of cracks were introduced in this paper .Finally ,a before-after study was conducted using site monitoring data .The results show that it is reliable and efficient to utilize the two remedial measures to repair different types of the cracks .
