Abstract
Since 1990s, a large number of in-service structures of water transport engineering in China have been close to their lifespan. Therefore, reinforcing and renovating constructions will be a long-term colossal task. Taking appropriate methods and effective means to evaluate the effect of the construction is a technical engineering problem which needs to be urgently solved. Based on the consolidation grouting construction of in-service shiplocks on the Karst Foundation, this paper makes a proper appraisal on reinforced effect by using a method combining field monitoring and numerical simulation. The results show that the measure of consolidation grouting has made a positive effect on improving the structural strain of shiplocks, which is in the safe state after construction. This comprehensive analysis method of field monitoring and numerical simulation is an effective means to validate the reinforced effect of waterway engineering structure.
