第六章土方工程中6.3条土方回填对土方回填作了4条规定,其中6.3.3条:填方施工过程中应检查排水措施,每层填筑厚度、含水量控制、压实程度。填筑厚度及压实遍数应根据土质,压实系数及所用机具确定。如无实验依据,应符合表6.3.3的规定。<–e<À?9Ífbbs.3c3t.coma† >±x Ѹ

在条文说明中:填方工程的施工参数如每层填筑厚度、压实遍数及压实系数对重要工程均应做现场实验后确定,或由设计提供。<–e<À?9Ífbbs.3c3t.coma† >±x Ѹ

<–e<À?9Ífbbs.3c3t.coma† >±x Ѹ

笔者认为对于大型及重要工程,必须按照该规范执行。笔者就自己监理的上述民用建筑土方回填工程,通过现场压实实验,来说明场地回填土方工程中压实实验的重要性,供参考。<–e<À?9Ífbbs.3c3t.coma† >±x Ѹ

<–e<À?9Ífbbs.3c3t.coma† >±x Ѹ

回填土的质量主要由现场回填土的压实密度来体现。<–e<À?9Ífbbs.3c3t.coma† >±x Ѹ

<–e<À?9Ífbbs.3c3t.coma† >±x Ѹ

土方回填前应清除基底的垃圾、树根等杂物,抽除坑穴积水、淤泥,验收基底标高。如在耕植土或松土上填方,应在基底压实后再进行,一般现场取土样,进行干密度实验,合格后进行回填土施工,对于软弱层,应根据设计要求进行换填处理后再进行施工。<–e<À?9Ífbbs.3c3t.coma† >±x Ѹ

<–e<À?9Ífbbs.3c3t.coma† >±x Ѹ

回填方土料应满足设计要求,对于需挖填场地,应立足于现场挖出的土料。所使用的土料必须现场取样,对土性变化大的场地,需划分出各自的区域,分别取样测定土样的最大干密度与最优含水量,回填时需分开回填,不能混淆。回填土前需测定土的含水量,如含水量大,需进行晾晒,降低含水量。如含水量小,需人工洒水,增加含水量,保证含水量接近最优含水量。<–e<À?9Ífbbs.3c3t.coma† >±x Ѹ

<–e<À?9Ífbbs.3c3t.coma† >±x Ѹ

施工场地地质情况说明:场地为残、坡积红粘土,分布均匀,厚度1~20米,变化较大,下伏灰岩,岩性变化不大,红粘土带弱膨胀性。挖方量约25万方,填方约22万方,石方约3万方,挖填基本平衡。<–e<À?9Ífbbs.3c3t.coma† >±x Ѹ

一、试验目的:<–e<À?9Ífbbs.3c3t.coma† >±x Ѹ

<–e<À?9Ífbbs.3c3t.coma† >±x Ѹ

测定土的含水量与质量密度的关系,从而确定该土的最优含水量与相应的压实干密度,根据击实试验确定的最大干密度之间的关系,掌握土方回填的压实遍数,给场平工作施工创造条件,以便保证土方压实的质量。<–e<À?9Ífbbs.3c3t.coma† >±x Ѹ

二、试验内容:<–e<À?9Ífbbs.3c3t.coma† >±x Ѹ

<–e<À?9Ífbbs.3c3t.coma† >±x Ѹ

本试验场地选在回填范围内,占地面积240m2, 试验场地根据工程的土方不同来源分为三部分(土样一、土样二、土样三)。试验日期为一天,参加人员为建设单位5人,监理单位4人,施工单位5人,共计14人。试验方法采用推土机找平,虚铺土厚度35cm,TY14型拖式振动碾压机,压实遍数4遍(振动碾4遍);6遍(平碾2遍,振动碾4遍)和8遍(平碾2遍,振动碾6遍)三次进行,其中铺土也是依次进行,根据土样来源和压实变数不同共取土样75件(其中在做试验时废了一件),实际试验土样74件。待三层土样都根据不同的压实遍数全部压实后又垂直取样18件(每个土样取6组),由于在取样过程中废了一件,实际试验土样17件,整个过程共做土工试验92件,取样均采用200cm3环刀进行。74件土样含水量与干密度关系见下表:<–e<À?9Ífbbs.3c3t.coma† >±x Ѹ

三、试验情况:<–e<À?9Ífbbs.3c3t.coma† >±x Ѹ

<–e<À?9Ífbbs.3c3t.coma† >±x Ѹ

1、所试验的粘土经环刀取样试验,干密度随含水量增加而减少。<–e<À?9Ífbbs.3c3t.coma† >±x Ѹ

<–e<À?9Ífbbs.3c3t.coma† >±x Ѹ

2、所试验的粘土天然含水量偏大,所做点处于最佳含水量锋值的右侧。<–e<À?9Ífbbs.3c3t.coma† >±x Ѹ

<–e<À?9Ífbbs.3c3t.coma† >±x Ѹ

3、从试验来看,碾压6、8遍所做点相对集中,离散点较少。<–e<À?9Ífbbs.3c3t.coma† >±x Ѹ

<–e<À?9Ífbbs.3c3t.coma† >±x Ѹ

4、从挖坑取样看,在第3层碾压后几处厚度有35cm,底部所取土样相对容易,眼观察土体稍松。<–e<À?9Ífbbs.3c3t.coma† >±x Ѹ

<–e<À?9Ífbbs.3c3t.coma† >±x Ѹ

5、挖坑取样中,有结合层分离情况。<–e<À?9Ífbbs.3c3t.coma† >±x Ѹ

<–e<À?9Ífbbs.3c3t.coma† >±x Ѹ

6、同层碾压中,光滑面结合处有水平分层现象。<–e<À?9Ífbbs.3c3t.coma† >±x Ѹ

<–e<À?9Ífbbs.3c3t.coma† >±x Ѹ

7、实验碾压不均匀,有的地方碾压遍数失真及实验操作不规范,导致少量数据在相同含水量的情况下,干密度相差偏大。<–e<À?9Ífbbs.3c3t.coma† >±x Ѹ

<–e<À?9Ífbbs.3c3t.coma† >±x Ѹ

8、垂直取样实验情况与分层取样实验基本一致,后续碾压对下层密实度基本无影响,不会增加下层的密实度。<–e<À?9Ífbbs.3c3t.coma† >±x Ѹ

<–e<À?9Ífbbs.3c3t.coma† >±x Ѹ

9、虚铺土厚度可按35cm实施。<–e<À?9Ífbbs.3c3t.coma† >±x Ѹ

<–e<À?9Ífbbs.3c3t.coma† >±x Ѹ

四、结论:<–e<À?9Ífbbs.3c3t.coma† >±x Ѹ

<–e<À?9Ífbbs.3c3t.coma† >±x Ѹ

1、本场地回填土质天然含水量偏大,回填时要减少含水量,含水量以击实实验的最优含水量为准,施工方要采取保证含水量措施。<–e<À?9Ífbbs.3c3t.coma† >±x Ѹ
2、建议施工回填碾压遍数不能少于6遍,8遍不经济。
<–e<À?9Ífbbs.3c3t.coma† >±x Ѹ

<–e<À?9Ífbbs.3c3t.coma† >±x Ѹ

3、需铺土厚度不大于35cm。<–e<À?9Ífbbs.3c3t.coma† >±x Ѹ

<–e<À?9Ífbbs.3c3t.coma† >±x Ѹ

4、每层结合层较光滑面处需采取抛毛处理。<–e<À?9Ífbbs.3c3t.coma† >±x Ѹ

<–e<À?9Ífbbs.3c3t.coma† >±x Ѹ

5、实验室操作人员要持证上岗,避免、减少实验误差。<–e<À?9Ífbbs.3c3t.coma† >±x Ѹ

<–e<À?9Ífbbs.3c3t.coma† >±x Ѹ

回填土施工时,施工、监理严格按实验结论指导施工:虚铺土厚度35cm,使用相同设备静压2遍,振动碾4遍(含抛毛处理的凸碾1遍),基层洒水后碾压,开挖回填土碾压前测含水量,分区域晾晒施工,试验员执证上岗,严格按实验规程操作,保证了回填土质量。后期基础施工时,人工开挖较难。特别是边坡较好:回填密实,容易成形,经过两个雨季后,5米高的边坡没有被雨水冲刷,保持了较好的形状,回填土施工受得了建设方的好评。<–e<À?9Ífbbs.3c3t.coma† >±x Ѹ
