Construction of urban green space system, promoting the construction of peripheral green space and protection of historical 2.2.深基坑工程监测的要求 在基坑开挖与支护工程中，为满足支护结构及被护土体的稳定性，首先要防止破坏或极限状态发生。破坏或极限状态主要表现为静力平行的丧失，或支护结构的构造产生破坏。在破坏前，往往会在基坑侧向的不同部位上出现较多的变形或变形速率明显增大。支护结构物和被支护土体的过大位移将引起邻近建筑物的倾斜和开裂。如果进行周密的监测控制，无疑有利于采取应急措施，在很大程度上避免或减轻破坏的后果。 3、编制依据: 3.1《建筑基坑工程变形技术规范》(GB50497-2009) 3.2《城市测量规范》(CJJ8-99) 3.3《精密水准测量规范》(GB/T15314-940) 3.4《工程测量规范》(GB 50026-93) 3.5《建筑边坡工程技术规范》(GB50330-2007) 3.6 《建筑基坑支护技术技术规程》(JGJ120-99) 4、工程地质概要: 4.1场地地层如下:第1层,耕土:灰黄色，层厚0.9,1.2m。主要成分为粉土，富含植物根系。该层在场地内大部呈连续分布，东北侧缺失。松散,稍密，稍湿。第2层，卵石:青灰色、灰黄色，层顶埋深0-1.2m，层底埋深10.8-25.7m，颗粒大小不均匀，形状以圆形、亚圆形为主，级配良好。一般粒径10,80mm，最大粒径100mm。中密,of vision Yibin formation in the Center surrounded by, organic dispersion band of bead-space layout structure, as leading development of the city to the East along the Yangtze River.

Construction of urban green space system, promoting the construction of peripheral green space and protection of historical 平均值，经检查无误后，检查偏离值: L=(β/ρ)*S (1) e) 精度估计 由于观测采用强制归心观测墩，以及小角度观测只利用测微器测定，所以误差主要来源于照准误差。 ?对距离S的精度要求 将L=(β/ρ)*S全微分，取中误差得: 2222222M=(m/ρ)* S+(m/ρ)* β (2) Lβs 相对于侧小角(β)，量测具有足够精度的边长S是比较容易的。因此，取(β/ρ)*S=3* (m/ρ)*β，代入(1)式，整理后，得: s m=(ρ* m)/3.16β (3) sL 由(1)式，得:β=(L*ρ)/S代入(3)式，整理后，得: m= m*S/3.16*L sL 写成相对中数误差形式: m/S= m/3.16*L sL 因此，要求m=0.5mm,而设偏离值L=40mm.则m/S=1/250,当Ls L=100mm,则边长相对中误差仅要求m/S=1/1000。 s 以1/2000的精度测量边长就满足测量精度要求。所以，在测小角时，边长需测一次即可。在以后的各期观测中，此值可认为不变。 ?观测小角(β)的精度要求 由(2)式略去右边第二项，得: M=(m/ρ)* S (4) Lβ of vision Yibin formation in the Center surrounded by, organic dispersion band of bead-space layout structure, as leading development of the city to the East along the Yangtze River.

Construction of urban green space system, promoting the construction of peripheral green space and protection of historical 新疆有色地质工程公司 盛达广场基坑监测方案 由于测小角的误差主要来源于照准误差，当小角度观测采用测回法时，一测回小角误差，由误差传播定律可知:m= m (5) βV 式中m为照准误差。 V 将(5)式代入(4)式， 得:M=(1/ρ)* S* m LV 由此可知，测小角的测量精度取决于照准误差。取眼睛视力的临界角为60″，则m=60″/V,V为放大镜放大倍数。本工程采用WILD V T精密经纬仪测小角，V=60倍，当测站到观测点的距离为S=120m时，3 测小角度对偏离值影响为0.58mm。由水平观测的误差分析可知:一般情况下，观测误差包括:仪器误差、测站对中误差、目标对中误差、角度观测误差、外界影响等。根据上述估算，可以满足边坡观测点相对于控制线的一次偏离值的测量精度为+/-3mm的精度要求。 6、监测频率: 6.1监测期限: 从基坑开挖开始，到?0.000施工结束。 6.2监测频率: 总次数 监测频率 (次) 监测项目 围护施工 井点降水 挖土 底 板 施 工 地下室施工 坡顶监测 1次/2天 1次/1天 1次/1天 1次/2天 坑外水位 布设测管 1次/1天 1次/1天 1次/1天 1次/2天 1次/1天 坑外道路监测 1次/1天 1次/1天 1次/2天 说明:根据工程需要，业主的要求及时调整监测频率。 - 7 - of vision Yibin formation in the Center surrounded by, organic dispersion band of bead-space layout structure, as leading development of the city to the East along the Yangtze River.
