摘要

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, China's port construction exhibits the development trend of large scale and deep water, and many ports are not the same type of seawall construction. Riprap construction of sloping breakwaters in open waters endures many complex factors from the external environment. Especially, coastal regions have distribution of deep and soft soil layers. With the increase in riprap amount and breakwater size, the real-time monitoring of settlement deformation is critical to control construction speed and project quality. According to the project situation and the characteristics of GPS technique, a real-time monitoring method for foundation settlement of sloping breakwater is proposed, including manufacture, laying and observation of subsidence monitoring equipments. The application of engineering example shows that the proposed method is suitable for the complex environment of riprap construction, and the settlement monitoring information can provide reliable basis for adjusting the intensity of riprap so as to ensure the safety of sloping breakwaters.
