5、測(cè)方案1.工程概況：6梅田區(qū)滑坡位于郴州市宜章縣，滑坡與市區(qū)道路僅有人行便道連接，交通條件較差。工作區(qū)位于郴州地南端，處于山區(qū)過渡地帶，氣候溫和濕潤，雨量較充沛，光照適宜，四季分明，屬亞熱帶濕潤氣候帶。降雨多集中在夏季，多暴雨、大暴雨，引發(fā)洪澇災(zāi)害，江河猛漲，山洪爆發(fā)。多年平均氣溫16.0℃，多年平均降雨量為972.6mm，每年降雨主要集中在5～9月，其間降雨總量占全年降雨總量的75%。多年月平均降雨量最高為7月的236.8mm，最低為1月的3.8mm，最大一日降雨量為220.5mm，最大雨強(qiáng)為70mm/h。工作區(qū)位于斜坡上部位，坡面沖溝不發(fā)育，無地表水流。2．目的與任務(wù)：a)目的
6、：用常規(guī)的或先進(jìn)的儀器和設(shè)備在野外滑坡、崩塌現(xiàn)場(chǎng)及其周邊地區(qū)進(jìn)行連續(xù)或定期重復(fù)的測(cè)量工作，準(zhǔn)確測(cè)定監(jiān)測(cè)網(wǎng)和形變監(jiān)測(cè)點(diǎn)的平面坐標(biāo)、高程或空間三維相對(duì)位移值，經(jīng)合理的數(shù)據(jù)處理提供監(jiān)測(cè)網(wǎng)和形變監(jiān)測(cè)點(diǎn)水平位移、垂直位移、裂縫及滑帶相對(duì)位移等動(dòng)態(tài)數(shù)據(jù)，為掌握滑坡變形規(guī)律、險(xiǎn)情預(yù)報(bào)、災(zāi)害防治、治理，達(dá)到治工程效果的檢驗(yàn)?zāi)康?；確?？⒐ば逼麦w的地形地物實(shí)際變形及變形趨勢(shì)，超前預(yù)報(bào)，保障斜坡體治理竣工后安全。b)任務(wù)：1)對(duì)斜坡體進(jìn)行地表（包括構(gòu)筑物頂部）的位移與沉降監(jiān)。2)通過監(jiān)測(cè)數(shù)據(jù)獲得滑坡局部和整體變形及變形趨勢(shì)，檢驗(yàn)滑坡穩(wěn)定狀況。3)與氣候、地下水位變化相聯(lián)系，分析滑坡、危巖變形與之的相關(guān)性
7、規(guī)律。4)在治理工程期間監(jiān)測(cè)斜坡體的地形地物實(shí)際變形及變形趨勢(shì)，超前預(yù)報(bào)，確保施工安全。5)提供治理工程效果評(píng)價(jià)報(bào)告，以及必要時(shí)的預(yù)警報(bào)告。3.執(zhí)行的技術(shù)規(guī)范與依據(jù)a)《工程測(cè)量規(guī)范》(GB50026-2007)。b)《建筑變形測(cè)量規(guī)程》(JGJ/T8-97)。c)《國家一、二等水準(zhǔn)測(cè)量規(guī)范》（GB/T12897-2006）。d)《精密工程測(cè)量規(guī)范》（GB/T15314-94）。e)《國家三角測(cè)量和精密導(dǎo)線測(cè)量規(guī)范》4.變形斜坡體監(jiān)測(cè)內(nèi)容、監(jiān)測(cè)方法和工作量布設(shè)4.1監(jiān)
