摘? 要:水文地質(zhì)情況是影響到巖土工程施工的關(guān)鍵性因素,但由于相關(guān)設(shè)計(jì)人員并未對(duì)此予以充分重視,使得地下水問(wèn)題頻發(fā),對(duì)巖土工程造成了巨大危害。開(kāi)展水文地質(zhì)調(diào)查能夠合理控制巖土工程施工過(guò)程中的風(fēng)險(xiǎn),加強(qiáng)工程建設(shè)的安全系數(shù),降低水文地質(zhì)災(zāi)害發(fā)生概率。據(jù)此可見(jiàn),探究巖土工程勘察中的水文地質(zhì)問(wèn)題能夠保障巖土工程的正常施工。本文首先分析了地下水對(duì)巖土工程勘察工作的影響,并介紹了水文地質(zhì)問(wèn)題的調(diào)查內(nèi)容,最后論述了水文地質(zhì)調(diào)查工作的注意事項(xiàng)。

Abstract: Hydrogeology is the key factor affecting the geotechnical engineering construction, but because the relevant designers do not pay enough attention to it, the groundwater problem occurs frequently, which causes great harm to geotechnical engineering. Carrying out hydrogeological survey can reasonably control the risk in the process of geotechnical engineering construction, strengthen the safety factor of engineering construction and reduce the probability of hydrogeological disaster. It can be seen that the exploration of hydrogeological problems in geotechnical investigation can guarantee the normal construction of geotechnical engineering. This paper first analyzes the influence of groundwater on geotechnical engineering investigation, introduces the investigation contents of hydrogeological problems, and finally discusses the precautions of hydrogeological investigation.

1? 巖土工程勘察概述
在巖土勘察工作中,勘察人員往往只重視巖土成分及構(gòu)造,忽視了水文地質(zhì)的相關(guān)問(wèn)題,僅從表面上的地質(zhì)現(xiàn)象進(jìn)行初步的評(píng)判。工程項(xiàng)目如位于水文地質(zhì)條件較好的區(qū)域,則不會(huì)影響到工程整體建設(shè)質(zhì)量,但如果選址在具有一定水文地質(zhì)問(wèn)題的區(qū)域中,加之沒(méi)有積極調(diào)查相關(guān)情況,則會(huì)致使后續(xù)的巖土工程出現(xiàn)一系列問(wèn)題,甚至直接導(dǎo)致工程繼續(xù)無(wú)法進(jìn)行,造成巨大的資源浪費(fèi)。從以上分析可見(jiàn),只有妥善處理水文地質(zhì)的相關(guān)問(wèn)題,才能保證巖土工程勘察的效果,提升巖土工程建設(shè)的質(zhì)量。
巖土工程勘察是工程施工前的必要步驟,通過(guò)對(duì)施工區(qū)域內(nèi)的地質(zhì)構(gòu)成及表現(xiàn),判斷其是否滿足工程建設(shè)需要。要充分測(cè)量各項(xiàng)地質(zhì)情況,并結(jié)合多項(xiàng)因素,對(duì)其中隱藏的風(fēng)險(xiǎn)作前期預(yù)防,據(jù)此確定出最為合適的施工位置。……
