如果挖掘深度超过4米，要指派一名土建工程师进行负荷计算、支护设计并在开挖期间监督支护施工。
If the excavation is more than 4 meters in depth, he will assign a Civil Engineer to provide a load calculation, shoring design and oversee the shoring construction during excavation.
挖掘机接触压力越大，偏心距对开挖深度的影响也越大。
It was indicated that the influence of eccentricity on excavation depth increased with the increase of contact pressure.
一般粘性土可自上而下分层开挖，每层深度以60cm为宜，从开挖端部逆向倒退按踏步型挖掘。
Generally clay can be excavated from top to bottom by layer with the appropriate depth 60cm. backward excavate from the end by stepping type.
