对于地下结构施工来说,圣彼得堡的工程地质条件是非常不利的。地下结构的优秀设计,必须遵循以下准则:适应施工场地具体地层条件、建筑理念、经济效益,以及工期要求。重要的是积累地下建筑设计和施工经验,在施工全过程对所建结构、对与工地临近的既有建筑物,采取综合监测措施,用监测数据评价计算的精确性和措施的有效性,其中包括基坑土方工程。下面叙述在圣彼得堡采用不同方法完成施工条件不同、深度不同的基坑工程。
For the construction of underground structures, St. Petersburg’s engineering geological conditions are very unfavorable. Excellent design of underground structures must follow the following guidelines: Adapt to the specific formation conditions of the construction site, architectural concepts, economic benefits, and duration requirements. It is important to accumulate experience in the design and construction of underground structures, to take an integrated approach to the structures under construction and to existing buildings adjacent to the site, and evaluate the accuracy of the calculations and the effectiveness of the measures with the monitoring data Including foundation pit earthworks. The following describes the use of different methods in St. Petersburg to complete the construction conditions of different pit depth of the project.
