It can be found that there is a stretch of landslide on the seafloor of outer continer- tal shelf and upper continental slope in the northern South China Sea by marine engi- neering geological investigation,The water depth is between 180 and 650m,The land- slide lies along the slope break at the outer edge of the continental shelf in NE-SW direc- tion,Its exact location is always interrelated closely with some seafloor scarp and ancient coast line at an ancient deltaic front.It is showed by shallow seismic profile,side scan sonar,bottom material sampling analysis and soil mechanical theory, that the inducing factors of landslide are landform slope,sediment characteristics,soil body gravity and bottom current speed and so on,Some areas even see multiple slidings。Thus we can say that the landslide areas are very unstable and can cause great geological hazard.Atten- tion should be paid to the landslide when carrying out marine engineering geological con- struction in the seafloor.

海洋工程地质调查发现,在南海北部外陆架和上陆坡海底,有大片滑坡,其水深范围约在180—650m之间,它们沿着陆架外缘坡折处呈北东—南西方向分布,其具体位置往往与古三角洲前缘的海底陡坎及古海岸线位置密切相关,大量浅层地震、旁侧声纳、底质取样分析和土体力学理论计算表明,本区滑坡主要是由于地形坡度、沉积物特性、土体自身重力、海底底层流速的大小等诱发因素而产生,而且有些滑坡带还具有多期滑动的性质,它们是区内海底很不稳定的地带,是一种重要的地质灾害因素,在海洋工程地质设计和实施时要引起注意。

Engineering geological zonation and related evaluation of the Pearl River mouth basin are an important result of the UNDP Project CPR/85/044.Integrated studies of multi-disciplines indicate the surveyed area which covers the segments of continental shelf(Ⅰ) and slope(Ⅱ)can be divided into five subzones.The unfavourable engineering geological factors in Subzone Ⅰ1 are low soil strength,strong hydrodynamics and many geohazards such as buried channels,shallow gas.The potential geohazards and geological coastraints in SubzonesⅠ2 include shelf valleys,ancient shoals,sand domes and pockmarks on the seafloor,and differential sedimentary faults within the subbottom.The major geological constraints in Subzone Ⅰ3 are characterized by development of paleao-delta sedimentary system,complexity in lithology and stratigraphic structure,frequent earthquakes with stong intensity.In subzone Ⅱ1,seafloor instabilities include landslides,slumps, turbility currents and dense growing faults.The constraints for seafloor engineering in Subzone Ⅱ2 are principally steep topography and occurence of mud diapir. In this paper,all engineering geoloical problems mentioned above are discussed in detail and assessed through the aspect of geomorphy,siol property,slope stability and neotectonics.

本文根据联合国开发计划署(UNDP)援华项目(CPR/85/044)资料撰写的。划分工程地质区及亚区的目的,在于了解区域工程地质条件的共性与差异性,以求在海洋开发中科学地利用和改造自然。本项研究是在大量地质-地球物理-土工测试基础上进行的,工作扎实,内容丰富,资料准确可靠。根据工程地质条件的相似性与差异性,将珠江口盆地划分为两个大区5个亚区,并研究了各区工程地质特征及主要问题。其中以中陆架混合土亚区工程地质条件最好,外陆架粗粒土亚区工程地质条件较好,上陆坡软土亚区工程地质条件最差,内陆架细粒土亚区和上陆架岩石、礁石亚区工程地质条件较差。本项研究成果为南海海洋开发与总体规划提供了科学依据,同时又促进了海洋工程地质科学的发展。
