| 摘 要： | 越来越多的连续墙工程提出了入岩要求，而现阶段广泛使用的连续墙抓斗入岩效率低下，针对这种状况，以抓斗抓取地层的特点为出发点，对其现阶段在岩石地层抓取效率低下的原因进行分析，然后以岩石破碎学为理论支撑，从抓斗自重、油缸闭合力、斗齿布置规格以及抓取方式等方面着手，提出了若干可用于提高抓斗入岩效率的改进建议。

| Abstract: | Rock-embedding is more and more required in diaphragm wall engineering. According to the low rock embedding efficiency of the grab widely used at this stage, take the characteristics of grabbed formation as the starting point, the analysis was made on the reasons of low rock embedding efficiency; with rock fragmentation theory as theoretical basis, some improvement suggestions were put forward in the grab weight, cylinder closing force, bucket teeth arrangement and grabbing mode. |

| Keywords: | underground diaphragm wall grab rock embedding bucket teeth arrangement |
