Application of Engineering Survey in Deep Foundation Pit Construction in Forest Area

Abstract

In summer, the dense leaves in the forest canopy strongly weaken the solar radiation, so that the
heat in the forest is less than that in the non forest. In addition, the total evaporation heat
consumption of forest is large, so the temperature is naturally lower than that outside the forest.
This brings great difficulty to the engineering survey in the construction of deep foundation pit.
In summer, the dense leaves in the forest canopy strongly weaken the solar radiation, so that the
heat in the forest is less than that in the non forest. In addition, the total evaporation heat
consumption of forest is large, so the temperature is naturally lower than that outside the forest.
This brings great difficulty to the engineering survey in the construction of deep foundation pit.
At present, there is no mature method to calculate the deformation of soil around the foundation
pit. Accurate and timely monitoring in construction can guide the excavation and support of
foundation pit. This is conducive to take timely emergency measures to avoid or reduce the
destructive consequences. This paper summarizes the application technology of engineering
survey in deep foundation pit construction. Combined with the monitoring data of a large
foundation pit, the application of horizontal displacement monitoring, building settlement
monitoring, internal force monitoring of enclosure system and earth pressure monitoring in
practical engineering is further studied. The experimental results show that the method can
improve the efficiency and accuracy of measurement.
