重慶市三峽庫(kù)區(qū)高切坡防護(hù)工程第九標(biāo)段天城沙河中學(xué)運(yùn)動(dòng)場(chǎng)高切坡勘察設(shè)計(jì)工作，經(jīng)國(guó)信招標(biāo)有限公司確定為我公司中標(biāo)的勘察設(shè)計(jì)項(xiàng)目。 本初步設(shè)計(jì)報(bào)告為：重慶市三峽庫(kù)區(qū)高切坡防護(hù)工程第九標(biāo)段天城沙河中學(xué)運(yùn)動(dòng)場(chǎng)高切坡防護(hù)工程初步設(shè)計(jì)報(bào)告。根據(jù)《三峽庫(kù)區(qū)重慶市高切坡防護(hù)工程地質(zhì)勘察與初步設(shè)計(jì)技術(shù)工作要求》，該高切坡失穩(wěn)危害程度很?chē)?yán)重，防護(hù)工程等級(jí)為一級(jí) 。 （ 4）國(guó)家發(fā)展與改革委員會(huì)《關(guān)于三峽庫(kù)區(qū)地質(zhì)災(zāi)害三期防治工作有關(guān)問(wèn)題協(xié)調(diào)意見(jiàn)的報(bào)告》（發(fā)改地區(qū)［ 2021］ 2918 號(hào)）。 （ 8）《長(zhǎng)江三峽工程建設(shè)移民條例》 （ 國(guó)務(wù)院令第 299 號(hào)， 2021 年 3 月 1日 ） 。切坡以上為沙河中學(xué)校園區(qū)，地形平坦。高切坡坡腳標(biāo)高 ，坡頂標(biāo)高 ，相對(duì)高差 1334m，高度變化為南邊高，向北高度逐漸降低。切坡坡高約 2334m，坡角 3076176。 主要工程量 根據(jù)場(chǎng)地邊坡的工程地質(zhì)特征，結(jié)合場(chǎng)地邊坡的平面布置要求，邊坡采用的治理方案為：錨桿噴混凝土支護(hù)。 200 名稱(chēng) 尺寸 混凝土（ m3） 梁長(zhǎng)（ m） 鋼筋型號(hào) 壓頂梁 1 300*300 6Φ 18 及 Φ 8 200 ４ 名稱(chēng) 尺寸 混凝土（ m3） 長(zhǎng)（ m）
