In underground construction, we really need to consider the presence of groundwater. Groundwater can interfere and even endanger the construction and excavation process. Usually, in the tunnel construction process, groundwater needs to be eliminated. So that the tunnel construction process can be carried out as safely as possible. Sometimes the construction of a tunnel in the middle of a city also needs some soil reinforcement to not disturb the surrounding buildings. One method that can be used to eliminate and strengthen excavated walls is ground freezing. Also, we know the dewatering process to eliminate the effects of groundwater by lowering the groundwater level. In this research, the effect of the dewatering and ground freezing processes will be calculated by stabilizing the diaphragm wall. Ground freezing will cause the bonding of soil particles to become stronger. Then the stability of the soil will be much better than dewatering. The result shows that ground freezing has the smallest deflection and moment. So, the stability of the ground freezing excavation has the best value. However, in terms of the price of ground freezing, it is still too high, so studies are needed to minimize the price.
