海塘隐患及防渗注浆效果检测技术应用研究
|
摘要
多年服役后的海塘已逐步暴露出一些安全问题,需要在查明其隐患的基础上实施注浆等防渗加固工程措施。针对某标准海堤的渗漏和注浆加固历史及以往勘察和探测情况,结合探地雷达、瑞雷波和地震映像等物理方法特点,分析了隐患探测及注浆效果检测的技术可行性,并实际开展了多种方法探测及资料综合解释工作。探测试验研究表明,采用基于不同物理场特征观测和分析的综合探测技术,不但可以查明海塘分层结构及内部不均匀等可能隐患的分布和性质,还可以通过浆液影响情况及注浆前后探测图像对比分析判断注浆效果。
Some safety problems caused by the hidden defects can be often found in seawalls constructed several years ago.It is necessary to detect the hidden defects in seawall body for consolidation by grouting process.It is still a challenge to improve the accuracy for locating and evaluating these defects due to the complicated structure of the seawall.Integrated geophysical exploration,including ground penetrating radar,relay surface wave and seismic imaging,had been applied to detect the hidden defects and evaluate the grouting effect for one standard seawall.Combined with some borehole exploration data,integrated interpretation was performed and the feasibility of the proposal was also discussed.Experimental results showed that the comprehensive interpretation based on different physical fields,could reveal the seawall inner structure,locate the hidden defect and some non-homogeneous regions in seawall.Meanwhile,combined with the previous seepage and grouting procedure records,the grouting and solid effect could be evaluated by comparing detection results acquired in different time periods.
