- Abstract:
- In a foundation pit engineering project in Zhengzhou, we monitored the axial force of soil nail andanchor by distributed optical fiber sensor, according to measured date ,and the role of the change of axial forceis discussed. The computation models for two compound soil nail supporting systems are established usingFL.AC3 D, and a construction process simulation of foundation excavating and support is conducted. Throughcomparative analysis of two models, the role of the micro-pile in the compound support structure can bedrawn, lastly, the simulation results were compared with the measured results, The results show that thiscompound supporting structure can give full play to the role of anchorage. Micro-pile can effectively control thestability and deformation of foundation ,and it can improve the stress status of soil nail and anchor force. Mean.while, the largest horizontal displacement of the foundation pit wall almost coincides with the most positivebending moment of micro-piles and maximum in the negative moment approximately coincides with slope feet offoundation pit side wall.
