【摘要】：近年来中国港口建设朝着大型化、深水化的格局发展,许多港口的海堤建设类型也各不相同。在开敞式无掩护水域进行斜坡堤的抛石施工,受外界不利影响的因素多而复杂。尤其沿海区域内大量分布深厚软泥土层,随着抛填量的加大和斜坡堤堤身的加高,实时监测地基沉降变形对于控制抛石施工速度和地基稳定极其关键。根据抛填施工和GPS测试技术的特点,提出一种斜坡堤地基沉降变形的实时监测方法,包括沉降监测设备的制作、埋设和观测。通过工程实例的应用表明,该方法能够适应现场抛石施工的复杂环境,所得沉降监测信息能够为施工单位调整抛填强度提供可靠的依据,确保了斜坡堤工程的安全。
[Abstract]:In recent years, the port construction in China has developed towards the pattern of large-scale and deepwater construction, and many seawall construction types are different. There are many and complicated factors which are adversely affected by the sloping levee in the open water without cover. In particular, a large number of deep soft soil layers are distributed in coastal areas. With the increase of the amount of dumping and the elevation of the embankment, the real-time monitoring of foundation settlement and deformation is crucial to the control of the speed of construction and the stability of the foundation. According to the characteristics of throwing construction and GPS testing technology, a real-time monitoring method for settlement and deformation of sloping embankment foundation is proposed, including the making, embedding and observation of settlement monitoring equipment. The application of the project example shows that the method can adapt to the complex environment of the site riprap construction, and the settlement monitoring information can provide a reliable basis for the construction unit to adjust the throwing strength and ensure the safety of the slope embankment engineering.
