Tunnel structure simulation test platform test pit structure and construction method thereof
The invention discloses a tunnel structure simulation test platform test pit structure which comprises a plurality of steel sheet piles which are located in a test pit and close to two adjacent edges of a metro interval side line, the steel sheet piles are arranged at intervals, and the lower ends of the steel sheet piles extend below the bottom of the test pit; the plurality of cement stirring solid piles are vertically arranged in the test pit to be excavated, and the lower end of each cement stirring solid pile extends to a sludge layer below the bottom of the test pit; the plurality of rotary excavating cast-in-place piles are uniformly divided into two rows and are arranged on the left side and the right side of the front-back axis of the test pit; the lower end of each rotary excavating cast-in-place pile extends below the bottom of the test pit and penetrates through the sludge layer; the concrete outer wall surrounds the test pit and is close to the steel sheet pile; the two concrete inner walls are located on the tunnel structure simulation test platform section in the test pit, one concrete inner wall is located on the left concrete outer wall side, and the other concrete inner wall is located on the right concrete outer wall side. According to the test pit structure, the safety influence on the metro section structure in the test pit excavation process is guaranteed.
本发明公开了一种隧道结构模拟试验平台试验坑结构，包括：多个钢板桩，位于试验坑内，且靠近地铁区间边线的两相邻边，多个钢板桩间隔排布，且下端伸至试验坑底部以下；多个水泥搅拌实桩，竖直设置于待开挖试验坑内，各水泥搅拌实桩的下端伸至试验坑底部以下淤泥质层；多个旋挖灌注桩，均分为两列，排布于试验坑的前后轴线的左右侧；各旋挖灌注桩的下端位于伸至试验坑底部以下，且穿过淤泥质层；混凝土外墙，绕试验坑一周，且靠近钢板桩；混凝土内墙，为两个，位于试验坑内隧道结构模拟试验平台段，一个位于左侧混凝土外墙侧，一个位于右侧混凝土外墙侧。该试验坑结构保证了在试验坑开挖过程中，对地铁区间结构的安全影响。
