广州地铁二号线越—三盾构区间的地层软硬不均,加之曲线多、坡度变化大,盾构掘进技术难度大,掘进方向与盾构姿态的控制困难,防止管片开裂和局部破损以及错台具有一定的难度。为了有效地控制掘进方向和盾构姿态,研究了盾构掘进方向发生偏差的原因,并对越—三区间盾构掘进的偏差实测数据进行具体分析,得出了偏差的原因和规律;研究了盾构掘进姿态的控制方法。为了防止盾构管片的裂损,采用数值模拟方法研究管片裂损的规律及其主要因素,提出了有效控制管片裂损的主要方法。

Hydraulic thrust system is an important system in a shield tunneling machine. Pressure regulation of thrust cylinders is the most important function for thrust system during tunnel excavation. In this paper, a hydraulic thrust system is explained, and a corresponding simulation model is carried out in order to study the system characteristics. Pressure regulation of a certain group’s cylinders has little influence on regulation of the other groups’ cylinders. The influence will not affect the process much during tunnel excavation. Pump displacement may have a greater effect on pressure regulation and oil supply flow rate should be adaptive to the system’s demand. A exacting situation is simulated to explain how pressure regulation works during tunnel excavation.
