针对沿渤海、黄骅港地区地质条件,场地地层较差,上部为素填土,以黏性土为主,其下在施工范围内依次为粉质黏土、黏土局部夹粉土层,地下水较多的情况,设计使用地下连续墙在旋流井基坑外侧作支护,另外主体结构采用逆作法施工,这样使外侧连续墙与逆作井壁共同作为基坑支护系统,不但安全可靠,而且施工较快。 According to the geological conditions along the Bohai Sea and Huanghua Port, the strata of the site are poor, the upper part is the plain fill, the cohesive soil is the main part, and the silt clay and clayey soil are in turn under the construction scope with more groundwater , The design of underground diaphragm wall is used to support the outer side of the foundation pit of the swirl well. In addition, the main structure is constructed by the reverse method, so that the external diaphragm wall and the counter-shaft lining together serve as the foundation pit supporting system, which is not only safe and reliable, but also Construction is faster.
