市政道路设计与古树保护的节点方案设计

为解决在盾构法预制拼装隧道内做超前探水预报的技术难题，系统开展地球物理场理论研究，论证各种方法的优劣，并针对盾构隧道管片衬砌结构开展实验，改进超前探水预报探测方法，为超前预报人员提供参考。实验结果表明：通过对CFC法的观测方式进行改进，避开了隧道内金属机具等产生的电磁干扰，对盾构机刀盘前方围岩含水情况进行综合预报。

Research and Practice of Advanced Water Exploration Prediction of Prefabricated Shield Tunnel

In order to solve the technical difficulties of making advance predictions in prefabricated shield tunnels, systematically carry out geophysical field theoretical research to demonstrate the advantages and disadvantages of various methods, and carry out experiments for different tunnels and different geological conditions, which can be used as a reference for other researchers. Experimental results show: through the improvement of the CFC observation method, the seismic wave method can be combined to comprehensively predict the water content of the surrounding rock in front of the cutter head of the shield machine.
