一、工程概况 我厂位于重庆附近,去年采用灰土井柱基础新建一幢1372米~2五层混合结构职工宿舍(图1、2)。该工程位于排水沟后面,人工回填杂土厚达6米,前后相对高差5米的坡地上。填土基底为耕土、亚粘土、黄粘土,部分地方浅露石灰岩。轻探次数为12～15次,地耐力为10～15吨/米~2,自然水面在原耕土下0.5～1米处,工程地质较为复杂。根据我厂施工条件,如采用50号水泥砂浆砌毛条
I. Project Overview Our factory is located near Chongqing. Last year, a new 1372m~2five-story mixed-use staff dormitory was built on the foundation of lime soil column (Figures 1 and 2). The project is located behind a drainage ditch and is artificially backfilled with a depth of 6 meters and a slope with a height difference of 5 meters. The filling base is ploughing, sub-clay, yellow clay, and some places are exposed limestone. The number of light explorations is 12 to 15 times, and the endurance is 10 to 15 tons/meter~2. The natural water surface is 0.5 to 1 meter below the original tillage, and the engineering geology is more complicated. According to the construction conditions of our factory, if using No. 50 cement mortar to build wool
