Composite sloping support system for deep foundation pit in deep soft soil field
The invention relates to the technical field of civil engineering foundation pits, and discloses a deep foundation pit composite slope supporting system for a deep soft soil site, which comprises a first-stage slope, a slope platform, a second-stage slope, a reinforcing body, a supporting pile and a pre-stressed anchor rod, and the first-stage slope, the slope platform and the second-stage slope are all horizontal or inclined slope surfaces; a reinforcing body is arranged at the bottom of the first-stage slope; the support pile is arranged at the position of the slope platform and close to the bottom of the first-stage slope, the support pile penetrates through the soft soil layer, a reinforcing body is further arranged on the side, close to the second-stage slope, of the support pile, and the reinforcing body is in lap joint with the support pile; the outer end of the pre-stressed anchor rod is fixed on the secondary slope, and the inner end of the pre-stressed anchor rod is obliquely inserted into the soft soil layer and is locally anchored in the reinforcing body; a reinforcing body is arranged at the bottom of the second-stage slope, and the width of the reinforcing body at the bottom of the second-stage slope is larger than that of the reinforcing body at the bottom of the first-stage slope. The method is reasonable in stress, strictly controls deformation of the foundation pit, and is suitable for deep foundation pit engineering with the depth of a deep soft soil site larger than 10 m and a relatively wide site.
本发明涉及土木工程基坑技术领域，公开了一种深厚软土场地深基坑复合放坡支护体系，包括一级放坡、放坡平台、二级放坡、加固体、支护桩、预应力锚杆，一级放坡、放坡平台和二级放坡均为水平或倾斜的放坡面；一级放坡的底部设有加固体；支护桩布置在放坡平台的位置且靠近一级放坡的底部，支护桩穿过软土层，支护桩靠近二级放坡的一侧还设有加固体，加固体与支护桩搭接；预应力锚杆的外端固定在二级放坡上，预应力锚杆的内端倾斜插入软土层内并局部锚固在加固体中；二级放坡的底部设有加固体，二级放坡底部的加固体宽度大于一级放坡底部的加固体。本发明受力合理，严格控制基坑变形，适用于深厚软土场地深度大于10m且场地相对开阔的深基坑工程。
