Land high-strength batholith construction method under complex geological environment
The invention provides an onshore high-strength batholith construction method in a complex geological environment, which comprises the following steps: dividing a cofferdam into a plurality of cofferdams through separation weirs, and constructing along a sand taking point, from a shore side to a sea side and from the sea side to a wharf cofferdam in sequence by taking the sand taking point as a starting point; the cofferdam construction comprises the following steps that the top edge line of a sand blowing bag and the laying bottom edge of a filling bag are firstly positioned, meanwhile, GPS positioning is carried out, and filling bag paying-off is carried out; each cofferdam is divided into a plurality of section layers, filling bag laying, sand blowing and drainage precipitation are sequentially conducted on each end face layer, after the first section is subjected to hydraulic filling, the first layer of the second section is subjected to hydraulic filling, and then the second layer of the first section is subjected to hydraulic filling again; a typical section layer is taken from each cofferdam, and the overall stability, the anti-sliding stability and the seepage stability of the typical section layer are calculated to judge whether the requirements are met or not; and before the cofferdam is constructed, a harbor basin and a foundation trench below the cofferdam are excavated, specifically, excavation is conducted downwards from top to bottom in a layered and segmented mode according to a slope line.
本发明提供了一种复杂地质环境下的陆上高强岩基施工方法，通过隔堰将围堰分为若干个，以取砂点为起点，按照沿取砂点，从岸侧到海侧，从海侧到码头围堰的顺序进行施工；围堰施工包括如下步骤：对吹砂袋的顶边线及填充袋的铺设底边先定位，同时由GPS定位，进行填充袋放线；将每个围堰分为若干断面层，对每个端面层依次进行填充袋的铺设、吹砂和排水沉淀第一段吹填完第一层后，吹填第二段第一层，回头再吹填第一段第二层；每个围堰中取一个典型断面层，计算典型断面层的整体稳定性、抗滑稳定性、渗流稳定性，以判断是否满足要求；还包括围堰施工前，围堰下方港池和基槽的开挖，具体是自上而下，分层分段按照坡度线向下开挖。
