地表沉降监测 监测软土层在预压荷载作用下的沉降量及其随时间的发展过程。

Monitoring of ground subsidence <br>monitoring of soft soil settlement in the pre-load pressure and with the development of the course of time. On the one hand, it can be used to evaluate the safety and rationality of the loading rate to prevent the soft foundation from being unstable due to the excessive loading rate; Settlement value after construction and determine reasonable unloading time. Number of subsidence observations: one subsidence observation point is set at approximately 2000 m2, and a total of 15 observation points are set.

Surface settlement monitoring <br>The settlement amount of soft soil layer under pre-pressurized load and its development process with time are monitored. On the one hand, it can be used to evaluate the safety and rationality of the loading rate, to prevent the soft-base instability caused by the loading rate too fast, on the other hand, the actual solidity of the soft base can be calculated by analyzing the observation results, the settlement value of the foundation work can be calculated and the reasonable unloading time is determined. Number of settlement observations: The settlement observation point slots on about 2000 m2 to set one, a total of 15 set.

Surface subsidence monitoring<br>Monitoring the settlement of soft soil under preloading and its development with time. On the one hand, it can be used to evaluate the safety and rationality of the loading rate and prevent the instability of soft foundation caused by the too fast loading rate. On the other hand, it can calculate the actual consolidation degree of soft foundation, calculate the settlement value of foundation after construction and determine the reasonable unloading time by analyzing the observation results. Number of settlement observation: one settlement observation point is set at about 2000 m2, with a total of 15.
